Reliability coefficients and Bland–Altman readouts for NP extent and intensity.

Test–retest reliability measures of NP extent and intensity
	ICC	95% CI	p value	Bias	LoA
NP extent [%]	0.96	0.76–0.96	<0.001	1.59	−9.78 to 12.97
NP intensity (NRS [0–10])	0.91	0.90–0.99	<0.001	0.02	−2.23 to 2.27

The intraclass correlation coefficient values (ICCs) are characterized as follows: “poor” < 0.40, “fair” = 0.41–0.59, “good” = 0.60–0.74, and “excellent” = 0.75–1.00, Bias = mean difference between the two measurements.
