Andrew Wakefield and Brian Hooker have lately been trying to manage a “cdc whistleblower” story. The idea has been covered a lot recently, here and elsewhere. So, rather than go into more introduction, let’s take a look at the complaint they recently filed with the CDC office of research integrity. It’s long, so I’ll bring up a few glaring problems with the complaint letter. These problems have for the most part already been discussed here at Left Brain/Right Brain.
The basis of their arguments has been that allegedly the CDC found a statistically significant result suggesting that the MMR was associated with a higher odds ratio for autism in African American boys. They argue that the CDC then changed their protocol (analysis plan) to avoid reporting on this result. Mr. Wakefield and Mr. Hooker have since added a similar argument for “isolated autism”–autism without comorbid conditions like intellectual disability. They claim the CDC hid those results as well.
So, what does the complaint say in specific? It’s long, but here’s an interesting and key part and a good place to start. Under the section titled “The Georgia Birth Certificate Cohort (GBCC): what was its stated purpose?“, Hooker and Wakefield quote the
[Exhibit 2, page 7, emphasis added] The Analysis Plan, “Statistical Analyses” states that “race” data were available for the entire sample:
The only variable that will be assessed as a potential confounder using the entire sample will be the child’s race.
[Exhibit 2, page 8, emphasis added]. Thus, “race” data came explicitly from the “school record” and not from the Georgia birth certificate/Georgia birth
records and was available for the “entire sample”.
The funny thing is that quote, “The only variable that will be assessed as a potential confounder using the entire sample will be the child’s race” doesn’t match what’s in the screenshot of the analysis plan that Wakefield included in his recent YouTube video (click to enlarge).

The plan actually states:
The only variable available to be assessed as a potential confounder using the entire sample is child’s race.
emphasis added.
See how “available to be assessed” in the actual plan has been changed into “that will be assessed” by Mr. Wakefield? Mr. Wakefield would like us to believe that the analysis plan called for a study to be reported broken down by race using all the kids in the study. He’s been arguing that since his first ugly “It’s like the Tuskegee experiment!” video. The thing is that the plan didn’t call for that. As I recently discussed, the sentence Mr. Wakefield misquotes was a statement of the limitations of the dataset they had (MADDSP) and explains why the CDC needed to get the birth certificate data to do a more thorough analysis.
As I also noted, the full paragraph references table included in the analysis plan made it clear that race was to be analyzed for the birth certificate sample, not the total sample as Mr. Wakefield is leading us to believe. The title of the table shows us that they were planning to report detailed data on the birth certificate group, not the entire sample.
What I find interesting is that Wakefield and Hooker are not just misinterpreting the statement as I originally thought. In the complaint they clearly changed what the statement said. Besides being wrong all on it’s own, this change tells me they know that phrase they latched on to ( “The only variable that will be assessed as a potential confounder using the entire sample will be the child’s race”) doesn’t come close to fitting in with his story. I don’t see this as an honest mistake.
The complaint also includes the “isolated autism” argument Mr. Wakefield recently put into another YouTube video. In this, Mr. Wakefield claims that all sorts of methods were used to hide an association observed for MMR and autism without other conditions like intellectual disability, cerebral palsy, etc.. In his complaint and video, Mr. Wakefield claims one of the methods used to hide this association was by limiting “other conditions” to only “MR” (mental retardation/intellectual disability). In the video Mr Wakefield gives us a fragment of an audio attributed to Mr. Thompson of the CDC saying, “the effect is where you would think it would happen. It is with the kids without other conditions, without the comorbid conditions.”
Mr. Wakefield even went on to say
But that didn’t seem to happen. They deviated further from the analysis plan by limiting the isolated group to only those with no mental retardation. Even changing the age categories and composition of the isolated subgroup may not have achieved the desired effect. Since, in the end, they simply omitted the relevant findings from the paper altogether
Emphasis added.
As I said before, I found this odd in that the CDC did report an apparent association in the raw data. The total sample/unadjusted data. To repeat a quote by Mr. Thompson, “It’s all there!”

It’s numerically almost the exact same result as Mr. Wakefield says was concealed. So, if it’s the same, how is it concealed? How is it omitted? Answer: it isn’t.
Remember that quote attributed to William Thompson from the video? Here’s a more full quote that’s from the complaint:
You see that the strongest association is with those [autistic cases] without mental retardation. The non-isolated [sic], the non-MR [mental retardation]…the effect is where you would think it would happen. It is with the kids without other conditions, without the comorbid conditions.
Mr. Wakefield wanted us to believe that by switching to autism without MR instead of autism without MR and/or other disabilities, the CDC were covering up the result. Not only did the CDC report on the result, this isn’t what Mr. Thompson was saying. Thompson is not saying, “hey look, we only used MR as a way to conceal the result.” He’s saying, in effect: when we looked at autism without MR, we saw this effect. It looks to me like Thompson is drawing Mr. Hooker’s attention to a result in the paper. Not describing an omitted result hidden from the public.
So, what is it? Did the CDC “simply omit the relevant findings altogether” as Mr. Wakefield stated in his video? No, they didn’t. Don’t take my word for it, take the word of Andrew Wakefield and Brian Hooker. In their complaint they state
2.7. The Group further deviated from the Analysis Plan by limiting the “isolated” group to only those without mental retardation, as published in The Paper.
Emphasis added.
So, we in the autism communities get one story in the video (the result was omitted), but in a legal document he puts the truth (the result was published in the paper).
And, how did the CDC accomplish all this alleged cover up in the story told by Mr. Wakefield and Mr. Hooker? Well, in part the CDC supposedly did this by creating a “revised analysis plan”. From the complaint:
Over the ensuing months and in contravention of the CDC’s own policies,10 they deviated from the Analysis Plan and introduced a “revised analysis plan”11
Wakefield and Hooker can’t provide us with that revised analysis plan. Here is reference 11 noted in the quote above:
11 See original notes of Dr. William Thompson of 9.6.2001: “Get revised analysis plan from Tanya.” Tanya Bashin – a relatively junior member of The Group – was the second author named on the DeStefano 2004 paper. [Exhibit 8] The revised analysis plan itself is not available
I discussed this recently as well. It’s not after “ensuing months” that Mr. Thompson wrote about the “revised” plan. It’s not after the data were analyzed (which the earliest dates given by the complaint are in November). The comment attributed to Mr. Thompson is dated September 6, 2001, the day after the plan was finalized.
Or, to put it another way: Mr. Wakefield and Mr. Hooker–the revised analysis plan is indeed available. It’s the one you are working from, dated Sept. 5, 2001.
In their complaint, Mr. Hooker and Mr. Wakefield disclose private details about Mr. Thompson which frankly have no real bearing on the complaint and should not have been disclosed.
The complaint is long, but it all hinges on the three major claims: (1) The CDC was supposed to do an analysis of the total group (not just the birth certificate group) by race, (2) that the CDC hid results on “isolated” autism and (3) that they deviated from their analysis plan, introducing a revised plan, to do this.
All three claims are false. And not false as in “I interpret them differently” but false as in “the very data Wakefield and Hooker depend on show them to be fabricated claims”.
