Dear Dr. Wun,Thank you for your careful review of our work and for pointing outthe error in the statistical terminology test. In our study, we used theWilcoxon scores (rank sums) test—equivalent to the Mann-WhitneyU-test—which is appropriate for comparing 2 independent groups.Unfortunately, in the Methods section, we incorrectly referred to it asthe Wilcoxon signed rank test, which is meant for paired data. Thiswas a labeling mistake, not a methodological one. We appreciate your attention to this detail, and we hope this let-ter will clarify the error for all readers.
