Notes: aData are expressed as median (interquartile range). Group comparisons were performed using the Mann–Whitney U-test. bData are expressed as mean ± standard deviation. Group comparisons were performed using the independent samples t test. cData are expressed as number (%). Group comparisons were performed using the χ2-test or Fisher’s exact test, as appropriate. P < 0.05 was considered statistically significant.
