Fig. 2

Box plots indicating distributions of wiping pressure and number of wipes by towel materials. Notes: Box plots of (A) wiping pressure (WP) and (B) number of wipes (NW) by towel materials. The median is denoted by the line within the box; 25th percentile, bottom border of box; 75th percentile, top border of box; variability outside the interquartile range, whiskers; and outside values, dots. The nurses applied WP and NW based on three classifications: ordinary (WP and NW applied in daily bed baths); weak (WP and NW for patients with vulnerable skin); and strong (WP and NW for patients with heavily contaminated skin). See Additional file 3 for details of statistical information; Interaction and main effect were analysed in a linear mixed model for two-way repeated-measures ANOVA (Effect size was calculated as partial η2); Wilcoxon signed-rank test showed that the number of wipes using disposable towel was significantly more often than that of cotton towel under the strong (a, P < .001) and ordinary (b, P = .018) condition. c, approximately 15% of the nurses performed patting only in the weak condition (Cotton towel; n = 84)
