Distributions of basic emotions. Distributions of basic emotions reported in relation to physical symptoms (visual analogue scale from 0 “No, not correct at all” to 10 “Yes, completely correct”) at baseline among clinical trial participants with persistent physical symptoms (PPS group; n = 159). The bold dashed lines represent the means for the PPS group, and the thin dashed lines represent the means for the healthy volunteers (n = 160).
