Data were presented as median (25th–75th percentile). P values were calculated using independent-samples Kruskal-Wallis test. Significance values have been adjusted by the Bonferroni correction for multiple tests. *Median P < 0.017, compared with groups TPVB. ^#Median P < 0.017, compared with groups LAI
