Trial By Error: More on that Disastrous Employment Paper from Professor Chalder and Colleagues

A few days ago, I wrote a post about yet another atrocious paper from Professor Trudie Chalder—this one called “Chronic fatigue syndrome and occupational status: a retrospective longitudinal study.” Professor Chalder and her colleagues seem constitutionally incapable of writing anything that isn’t marred by massive flaws. In this case, as I noted the other day, besides the fact that she and her colleagues misrepresented their findings by messing up their denominators in expressing percentages, they omitted any reference to the null findings on employment from the PACE trial—an egregious lapse.
They also seemed confused about whether they diagnosed patients using the 2007 guidelines from the National Institute for Health and Care Excellence for CFS/ME, or using the 1991 Oxford CFS criteria. They mentioned NICE in the text but the cited reference was the 1991 paper. The differences between the case definitions are significant, so this confusion is jarring
