The differences between the NC and si groups were statistically highly significant at 24 h ( p < 0.001), 48 h ( p < 0.0001), and 72 h ( p < 0.0001).

The Wilcoxon signed‐rank test for the overall paired difference did not reach statistical significance ( p = 0.097), and we therefore refrain from describing this result as a positive finding; we treat it instead as a nonsignificant directional difference that, given the modest sample size ( n = 33) and the wide CIs around the per‐patient proportions, is best regarded as exploratory and hypothesis‐generating.
