The "14" Studies Written by a Danish vaccine company, the study made a mockery of the data, a problem the authors themselves warned of. And, the CDC engineered the entire study. This one goes beyond useless, it was fraudulent to run the numbers this way, and they knew it.

The purpose of this review is to examine these six publications [21–26] which were “overseen” by the CDC and which claim that prenatal and early childhood vaccine-derived Thimerosal exposures are not related to the risk of a subsequent diagnosis of autism or autism spectrum disorder (ASD). This review analyzes possible reasons why their published outcomes are so different from the results of investigations by multiple independent research groups over the past 75+ years. The review begins with an examination of the Madsen et al.  study.

[2011 Nov] Exposed: CDC deliberately manipulated, covered up scientific data showing link between vaccines containing mercury and autism
[2011 April] Indicted Researcher Poul Thorsen:
Autism Speaks' Original Trailblazer In May 2000, one week before the
infamous Simpsonwood meeting, Poul Thorsen suggested blazing a new trail to the
CDC - disguising the role of vaccines in the autism epidemic by using data from
Denmark. He made this suggestion to CDC staffer, NAAR/Autism Speaks scientific
adviser and (Bernie) Marcus Institute board member Dr. Marshalyn Yeargin-Allsopp..
The CDC funded the project; NAAR supplemented.
Poul Thorsen crafted the plan to use Denmark vaccination data despite the fact that CDC, Thorsen and the NAAR board all knew that Denmark's vaccine schedule then, and now, is not remotely similar to the US vaccine schedule. The results of the Denmark studies helped the CDC out of a tough spot and over the past decade, Thorsen's studies were utilized by the CDC repeatedly to falsely reassure the American public about the safety of vaccines. CDC certainly owed Thorsen.
In 2002, NAAR, who later merged with Autism Speaks, provided $105,300 to supplement the CDC project. NAAR walk money helped Thorsen blaze his trail of using data from Denmark to disguise the potential role of vaccines in the autism epidemic.
[2010 March] First Fraud: Dr. Poul Thorsen and the original “Danish Study” By J.B. Handley It’s hard to put into words how dishonest and outrageous a study this is, and I knew after reading it that we were in for a long fight: if scientists will lie this explicitly and call it a study and if Pediatrics will publish something this dishonest, they are playing to win at all costs.

[Nov 2002] New England Journal of Medicine Study on Autism-MMR Vaccine in Denmark NOT Definitive
Letter by Sandy Mintz
"All the sources of error identified in the (Danish) study distort it in the same direction: obscuring the role of the MMR vaccine and exonerating it from any suspicion that it may cause autism. This strongly indicates deliberate fraud. The reason is not hard to guess. Most of the authors of the report are medical doctors and it is safe to assume that they are - or have been - ardent pro-vaccinators. By now they should be well aware of the many scientific studies of the injuries caused by vaccines. They will know that there is now an autism epidemic, that only the vaccinated are affected and that autism always occurs after vaccination and not before. In other words the authors of this report are people with blood on their hands, who fear the retribution of parents, whose children they have killed, mutilated and rendered autistic. People who are prepared to kill and injure helpless children for money will hardly hesitate to lie and cheat if it will keep them out of jail and enable them to avoid paying compensation to their victims. This report is a desperate and despicable attempt by child abusers to remove the noose that is tightening around their necks. Their report (and this one) belongs in the hands of the prosecutor."-----Ulf Brånell
Again, it’s symptomatic of that Danish study where you did a Thimerosal causal on a population that doesn’t have an autism epidemic, and you find nothing. So this is, again, it’s part of the government; look where you won’t find anything and when you don’t find anything, then sell it to the American public because if, “Well, if we didn’t find anything therefore it’s safe.” And you’re going to see that come out and that is done by taxpayer dollars and people ought to be extremely mad about it. Interview of Dr. Boyd E. Haley by Teri Small:
The first new study, by Dr Samy Suissa, an epidemiologist at McGill University, Montreal, who looked at the same data the Danish doctors used, concludes that children who received the triple jab were 45 per cent more likely to develop autism than those who were not given it. A second piece of research - by Dr Fouad Yazbak, an American paediatrician - shows a 400 per cent rise in autism after the introduction of MMR in Denmark, even after taking into account greater awareness of the condition. And a third study by Dr Andrew Wakefield, who first made the link between MMR and autism in 1998, and Dr Carol Stott of Cambridge University, shows autism cases in Denmark have increased by 14.8 per cent each year since MMR was introduced. [Media 29 August 2004] There IS a link between the MMR jab and autism, claims new research
Madsen’s mercury study published by PEDIATRICS in September, 2003 has been described by the IOM Vaccine Safety Review Committee as “well designed” and has been consistently used by government agencies worldwide as proof the vaccine preservative thimerosal does not contribute to autism rates. Jeffrey Trelka exposes the study’s fatal flaws and provides proof of the mercury misinformation campaign that has been waged by the CDC, IOM, and the editors of the AAP journal. As he quotes C. S. Lewis, "The greatest evil is... conceived and ordered in clean, carpeted, warmed, and well-lighted offices, by quiet men with white collars and cut fingernails and smooth-shaven cheeks who do not need to raise their voice."

Of the 5th, Madsen, it correctly identified the confused data set, which in fact included amongst the vaccinated non-autistic group (1) infants to young to have been vaccinated (2) children too young to have been diagnosed. There have been various attempts to re-interpret the data, but the most independent was Prof Suissa of McGill who wrote to NEJM suggesting that the vaccinated group were 45% more likely to have autism. Suissa's letter was not published by NEJM, and can be found here: http://www.jpands.org/vol9no3/stott.pdf--John Stone
