First up this month on PLOS Blogs, I tackled peer review again: this time, weighing up anonymity and openness in publication peer review. I found 17 relevant comparative studies, most of them controlled trials - as well as the blog post, I added them to a comment on PubMed Commons.
Then something I sure didn't see coming: some journalists decided to do a trial of chocolate for weight loss as a hoax to expose corruption in the diet research/journalism complex. Mostly, it seemed to me, they showed failures of medical and journalist ethics, and their own conflicts of interested. My post is called, Tricked: the ethical slipperiness of hoaxes.
And on Tumblr, the most misunderstood and misused statistical concept of all: statistical significance. On PubMed Commons, I commented on a paper on publication bias in Cochrane systematic reviews.
