Cheney said that they didn't test the sickest patients b/c the

researchers did not allow anyone on meds to participate. That is

absolutely false. Of the 38 patients (18 severe, 20 moderate), 19

patients were on meds at the time of testing.

Cheney's representation of the Q data here too are inaccurate. Here

are the data from the paper:

Sendentary Contrls: upright: 6.9 supine: 4.8

Mod CFSs: upright: 6.8 supine: 4.5

Severe CFSs: upright: 5.7 supine: 3.8

I suggest you take a look at the original paper, the link to which I

posted earlier, as there are many diffs between Cheney's

representation of the study & the actual study, not only in

methodology & data, but also in conclusions. Hope this helps

clarify a few things.

Yes, thanks duramater. I've used your link and printed it out and will

study it carefully.
