Following publication of the Shattuck paper casting doubt on the evidence for an autism epidemic:

The mean administrative prevalence of autism in US special education among children ages 6 to 11 in 1994 was only 0.6 per 1000, less than one-fifth of the lowest CDC estimate from Atlanta (based on surveillance data from 1996). Therefore, special education counts of children with autism in the early 1990s were dramatic underestimates of population prevalence and really had nowhere to go but up. This finding highlights the inappropriateness of using special education trends to make declarations about an epidemic of autism, as has been common in recent media and advocacy reports.

The usual suspects have begun to trot out the usual ploys to try and misrepresent and obscure. The National Autism Association write:

A study published today in Pediatrics, “The Contribution of Diagnostic Substitution to the Growing Administrative Prevalence of Autism in US Special Education,” suggests that autism diagnoses haven’t actually risen over the past two decades, despite *growing and credible scientific evidence to the contrary*. In addition to the study’s *weak methods and erroneous conclusions*, questions have now arisen over possible *failure to disclose conflicts of interest* and *recent findings that data from previous autism projects with which current study author Paul Shattuck has been associated were fabricated*.

So first lets tackle the ‘growing and credible scientific evidence to the contrary’. Where is it? Where does it exist? Note that NAA totally fail to name, or even _reference_ this ‘growing evidence’.

They also mention ‘weak methods and erroneous conclusions’ yet again failing to illustrate what these ‘weak methods’ are or why they are weak. As far as erroneous conclusions go, that seems to be NAA double-speak for ‘things we disagree with but can’t back up’.

But what about ‘failure to disclose conflicts of interest’? NAA say:

Although the article states that Dr. Shattuck has indicated he has no financial relationships relevant to the article, NAA has learned that he was a Merck Scholar Pre-doctoral Trainee from 1999-2003, and in 2003-2004 he successfully applied for $530,000 from the Centers for Disease Control and Prevention (CDC)

Somebody remind me again – what year is this? 2003? 1999? Or is it 2006? two years after Dr Shattuck had *an alleged* financial relationship with Merck.

UPDATE: Orac Provides the following: _”Oooh, Shattuck received money from the evil Merck to support his training! Except that the Merck we’re talking about seems to be not the evil drug company but rather a nonprofit organization, the John Merck Fund, which supports research into a variety of areas, particularly developmental disabilities.”_

By comparison, Wendy Fournier, president of the NAA has an ongoing, established financial relationship with David Kirby – author of Evidence of Harm – as does Safe Minds. Claire Bothwell, Chair of the NAA, works(worked?) for Waters and Kraus, lawyers who solicit thimerosal plaintiffs over the internet.

Lastly, what about ‘recent findings that data from previous autism projects with which current study author Paul Shattuck has been associated were fabricated’? Sounds damning, until you read on:

Although he was not personally implicated, Dr. Shattuck’s former research partner, a graduate student at the University of Wisconsin’s Waisman Center, was recently disciplined by the Health and Human Services Office of Research Integrity for scientific misconduct due to fabrication of data. Dr. Shattuck and others published several articles and delivered scientific presentations using data from the project in question

So someone that Shattuck once quoted got themselves in trouble. Thats hardly what I’d call

…with which current study author Paul Shattuck has been associated…

There’s also no indication that these studies Shattuck referenced, or the presentations he made which referenced them had _anything at all_ to do with autism.

The press release goes on to say:

Given the rocky history of the CDC and the autism community, failing to mention the author’s ties to this agency is a glaring omission that requires an explanation,” commented NAA board chair Claire Bothwell. “Clearly, the CDC has a vested interest in deflecting attention from the possibility that children injured by mercury-containing vaccines ended up with autism diagnoses which fueled autism rates off the charts

First of a message to the NAA, Safe Minds, Generation rescue etc – *you are not the autism community* . You represent a small subset of parents. Thats it. What you have is a good PR campaign and a few pet journalists.

Secondly, its clearly the case that several anti-vaccine groups such as NAA, SafeMinds etc are beginning to get very very jumpy and have a vested interest in deflecting attention away from the increasing evidence that there has been _no epidemic of autism_ and that autism is not caused by thiomersal in vaccines. Autism rates are not ‘off the charts’ – the charts were simply never big enough to start with.

These groups need to stop politicising the issues, need to stop painting themselves as ‘the autism community’ and need to stop this pointless and utterly transparent attack on any credible science that undermines their isolationist position.
