Probability of Treatment Retention by Group
Estimated by the Kaplan-Meier method overall probability function. C-OLP (n = 77) overall probability, 0.75 (95% CI, 0.66-0.86); TAU (n = 54) overall probability, 0.59 (95% CI, 0.48-0.74). C-OLP indicates conditioned open-label placebo; TAU, treatment as usual.Mixed-effects models showed that group C-OLP reported better sleep quality (global C-OLP PSQI score, 8.12 [0.48] vs 9.9 [0.46] for TAU;
