Random and fixed‐effect meta‐analytical models were used to evaluate the study outcomes. Sensitivity analysis, funnel plot and meta‐regressive techniques were carried out to explain the heterogeneity and selection bias between the studies.

Results  Six studies, consisting of a total of 488 patients (223 IRA and 265 SC) were included. Analysis …
