I do wonder how many people here actually bothered to *read* the paper...
It's important to keep in mind that the authors of this paper were *not* responsible for the experimental design behind this data. In fact, they're reanalyzing data that they were only able to obtain by suing Monsanto, and that Monsanto had previously used to claim their GMO strains were safe.
Yes, there definitely are significant problems with the experimental design and statistical analysis used *by Monsanto*, and the authors clearly point this out. For one, Monsanto never tested a large enough number of animals and at a large enough time points and doses to have a sufficient statistical power to be able to make the claims that they did. In addition, it turns out that Monsanto didn't even consistently apply the statistical methods they described.
Lastly, the authors of this paper showed that by analyzing Monsanto's data more rigorously, they are able to detect some significant differences between the GMO and control-fed animals (mainly in those fed 1/3 of their entire diet in GMO corn), and then speculate that those differences *could* be due to residual Roundup or Bt toxin in the GMO corn.
That last part is definitely the weakest of the paper, but the main take-home message here is *not* that GMO corn is bad for your health, but that Monsanto's own data and analysis was entirely insufficient to claim safety.
(For the record - I happen to believe that the vast majority of GMO foods are actually safe. But I also happen to believe that multi-billion dollar companies like Monsanto - or drug companies - should be held to account if they do shoddy science when trying to prove that their products are safe...)
