The PACE Trail Protocol states: “We propose that a clinically important difference would be between 2 and 3 times the improvement rate of SSMC.”
The chart below shows actual, individual CHANGES between baseline (start of the trial) and the 52 week Outcome for 148 participants in the CBT and SMC groups. Added, are CHANGES in the SMC (Control Group) multiplied by 2 (blue) and 3 (green). These show the difference expected by the researchers. If CBT had been effective, the red line would be between or above the blue and green lines at all points.
CBT failed in the PACE Trial – the data proves it. No torture was involved, I politely asked the data whether CBT lived-up to White et al’s expectations. It did not come close. The only way to claim a treatment-effect from these outcomes is by denying the data.
