OR: odds ratio; MD: MD: mean difference; VAS: visual analog scale; AAS: amount of analgesics used; HHS: Harris Hip Score; ER: effective rate; AE: adverse events; the experimental design had a large bias in its random, distributive findings or was blinded; the confidence interval overlapped less, the value of the heterogeneity test was very small, and the I2 was larger; the confidence interval was not narrow enough, or the simple size was small; funnel graph asymmetry.
