Extended Data Fig. 5: The effect of intravenous iron on all-cause mortality over the complete length of follow-up (pB = 0.221, I2 = 16%).

The forest plot illustrates the effect of IV iron on all-cause mortality over the complete length of follow-up using a Bayesian random-effects meta-analysis. Data are presented as hazard ratios (HRs) with 95% credible intervals (CIs). Sensitivity analyses were conducted by omitting the FAIR-HF and CONFIRM-HF studies and by applying alternative half-normal (HN) priors. n / N: number of events / number of subjects in group.
