Impact of InterTAN compared with PFNA on operating time, fluoroscopy time, blood loss and other complications. Forest plots. The forest plots show the odds ratio (OR) calculated by the random effects model or the mean difference (MD) calculated by the fixed effects model. Squares represent individual study effects and diamonds represent the summary effect from the meta-analysis. Horizontal bars represent 95% CIs and the vertical line in plot is at 1 for OR and 0 for MD, corresponding to the null hypothesis of no effect. I2 = test of heterogeneity, CI confidence interval, df degree of freedom, M-H Mantel–Haenszel
