Pain intensity (NRS) and PPT in patients with CWP (n=18) and in CON (n=19)

Variables and locations	CWP	CON	Statistics (P-value)	Cohen’s d
NRS (0–10)	4.4±2.3	0.0±0.0	<0.001	2.71
PPT (kPa/s)
Trapezius (right side)	238.5±133.1	526.8±102.1	<0.01	2.43
Trapezius (left side)	219.3±119.3	538.5±94.8	<0.01	2.96

Notes: Values are presented as mean ± 1 SD, and furthest to the right is presented the results of the statistical comparisons (P-value) between CWP and CON together with the absolute value of Cohen’s d.

Abbreviations: CON, controls; CWP, chronic widespread pain; NRS, numeric rating scale; PPT, pressure pain threshold; SD, standard deviation.
