    Got to admit I didn't read this, other than the first couple of paragraphs, but thought it might interest others here.

    This would be an important step forward.

    With the amount of bad research out there lately, I would suggest going with 0.005. This still won't prevent p-hacking, of course.

    Well, as an exercise, in the Stanford study the following met the p < 0.005 threshold:

    FDR-adjusted p-values:

    ME.CFS patients vs. Controls: Resistin, TGF-β [Both p-values were actually 0.0052, or 1 in 192 vs. 1 in 200]

    Unadjusted p-values:

    ME/CFS patients vs. Controls: Resistin, TGF-β

    Mild vs. Controls: Leptin, Resistin
    Moderate vs. Controls: ICAM1
    Severe vs. Controls: IL-7, IL-13, NGF, Resistin

    Linear Trend Analysis: CCL11, CXCL10, G-CSF, GM-CSF, IFN-γ, IL-4, IL-5, IL-7, IL-12p70, IL-13, IL-17F, Leptin, LIF, NGF
    Non-Linear Trend Analysis: ICAM1, Resistin

    I suppose you mean p<0.005 ;)
