Wow, leib, you should try stating a fact that you can show to be true. You will be shocked at how good it feels to do so.
You are the only one who here who is promoting the quackery of quacks who have stated provable lies. You need to get away from such stuff.
Alright, let's try to be more respectful to each other. I apologize for lashing out, but this is an issue that drives me nuts. Here are the reasons why I find the Mawson study to be completely unreliable and most likely fraudulent. Now, if you would like to point out that this is from a blog, I already know, but the points made are completely valid and alarming. Most alarming is the fact that it was published on a
pay-to-publish site,
Open Access Text. There is no way to argue that OAT is a valid scientific journal, so it goes further to explain why the study itself is unreliable.
(from
Why this vaxed v. unvaxed study is not valid: Update: Study retracted AGAIN.)
At
Respectful Insolence blog, ORAC (aka Dr David Gorski, oncologist) rightfully criticized the methodology of the study as well as the fact that a chiropractor was used to peer review an epidemiology study. Chiropractors are not the peers of epidemiologists. ORAC also noted that this study was funded by
Generation Rescue, a notoriously antivax group.
These are problems. Real problems. So, the original journal, Frontiers, took note and pulled the study.
Now, months later, the study has been published in a pay-to-publish journal online called Open Access Text. Reputable scientists don’t pay to publish their studies. Journals like Pediatrics or Vaccines or The Lancet don’t require authors to pay and they are considered far more respectable when it comes to considering authors for professorship positions. Scientists know these facts. They know that
publishing in a predatory journal is not a good career move.
So, what happened after this study was pulled by Frontiers? It was submitted to Open Access Text, a predatory, pay-to-publish online journal, and published this week. And it is being spammed everywhere as a valid study.
It is not valid and here is why.
One: It was funded by two known antivax groups, Generation Rescue, Inc., and the Children’s Medical Safety Research Institute (CMSRI). Both are well know to be opposed to vaccines. CMSRI is funded by the
Dwoskin Foundation, who are big money behind a lot of antivax operations. This does not negate the results, by any means, but it does beg the question – what was the motivation for the study. By the same token, I would look very skeptically at any study published by a pharmaceutical company.
Two: Read the introduction. The authors went into the study assuming vaccines cause grave harm.
” The aims of this study were 1) to compare vaccinated and unvaccinated children on a broad range of health outcomes, including acute and chronic conditions, medication and health service utilization, and 2) to determine whether an association found between vaccination and NDDs, if any, remained significant after adjustment for other measured factors.” That is serious bias.
Three: The study design was flawed. “
The study was designed as a cross-sectional survey of homeschooling mothers on their vaccinated and unvaccinated biological children ages 6 to 12. As contact information on homeschool families was unavailable, there was no defined population or sampling frame from which a randomized study could be carried out, and from which response rates could be determined. However, the object of our pilot study was not to obtain a representative sample of homeschool children but a convenience sample of unvaccinated children of sufficient size to test for significant differences in outcomes between the groups.” Right from the start, Mawson, et al, admit that they aren’t really able to do a good, quality study. “
A number of homeschool mothers volunteered to assist NHERI promote the study to their wide circles of homeschool contacts.” This is also problematic. They had participants promoting the study to their own friends. How did they account for bias? They did not.
Four: Methods were flawed. The authors categorized the children as unvaccinated, partially vaccinated, or fully vaccinated based only on word of the mothers. They did not consult medical records. Mothers were then asked to indicate which illnesses their child had had but no medical records were consulted. This data was analyzed statistically but how can they analyze data they have not verified as accurate? They purposely did not use medical records because they said that would have led to low participation.
Five: The limitations. Oh my, the limitations. “
We did not set out to test a specific hypothesis about the association between vaccination and health.” So, this was not even science.
