Fig. 6: Correlations between behavioral and neural placebo-induced reductions.

From: Placebo treatment affects brain systems related to affective and cognitive processes, but not nociceptive pain

Fig. 6

Placebo-induced neural reductions (Control - Placebo) in the (A) NPS or (B) SIIPS, as a function of the behavioral analgesia (pain ratings Control - Placebo) for each stimulus intensity level (color) and modality. Each dot is a participant. Lines represent linear smoother, with the 95% confidence interval shaded in gray. Asterisks represent significance of the correlation (mixed-effects model, uncorrected): *p < 0.05, **p < 0.01, ***p < 0.001 (Thermal: N = 367 participants; Mechanical: N = 368 participants).
