Intra-rater reliability of the wiping pressure performed six times for two types of skin dirt

Skin dirt	SEM	ICC	95%CI		P-value
			LL	UL
Oily	2.57	0.990	0.985	0.994	<.001
Aqueous	2.76	0.989	0.984	0.994	<.001

Notes: Aqueous Wiping pressure for pseudo-aqueous dirt; CI Confidence interval, ICC Intraclass correlation coefficients, LL Lower limit, Oily Wiping pressure for pseudo-oily dirt, SEM Standard error of measurement, UL Upper limit
