#Continuous variables were described as median (interquartile range) and Wilcoxon rank-sum test was used, *P value <0.05. The total number of patients was 127 in CFNB group and 123 in PCIA group for in-hospital pain evaluation, while 109 patients in CFNB group and 102 patients in PCIA group were included in the analysis of chronic pain.
