  1. We are presenting data stratifying the ESS data by scores 16 or higher; this was the median value for SDB patients fulfilling diagnostic criteria for CFS and/or FM. We are presenting Beck data two ways: with the cut off at 20 [moderate depressed mood] and at 14 [mild depressed mood] if data differed from those using the 20 cut off.
