The table shows the p values obtained by the Wilcoxon rank sum test, the effect sizes by Cliff’s delta, the AUC, and the correlation coefficient between the HAM-D and EALVI for each phrase of both facilities. The minimum p-value, maximum effect size, maximum AUC, and maximum correlation for each hospital are shown in bold fonts.
***(p < 1.0 × 10⁻³), **(p < 1.0 × 10⁻²), *(p < 5.0 × 10⁻²).
