Table 2.

Bates-Jensen wound assessment scores in the two groups at different time points [points, M (P25, P75)].

Group	Initial visit	Week 1	Week 2	Week 4	Time factor F/P	Group factor F/P	Time × Group F/P
Intervention group (n = 34)	30.00 (25.75, 31.00)	24.50 (22.00, 29.00)	19.00 (14.00, 25.00)	13.50 (6.00, 20.00)	77.304/<0.001	11.492/0.001	4.075/0.010
Control group (n = 34)	31.00 (27.00, 33.00)	27.50 (24.75, 31.00)	23.00 (20.75, 28.00)	21.00 (17.00, 24.00)
Mann–Whitney U	432.000	397.000	380.000	293.500
Z value	−1.797	−2.227	−2.432	−3.521
p-value	0.072	0.026	0.015	<0.001

Data are presented as median (P25, P75), as the Week-4 Bates-Jensen scores departed from normality (Shapiro–Wilk p < 0.05 in both groups). The two-way repeated-measures ANOVA was retained as the primary analysis given its robustness to moderate departures from normality with equal group sizes (n = 34 per group); the main effects of time, group, and the time × group interaction are shown in the last three columns. Mann–Whitney U tests at each time point were performed as non-parametric sensitivity analyses (Bonferroni-adjusted significance level α = 0.0125). M (P25, P75) = median (25th percentile, 75th percentile).
