Figure 4 Major amputation -free survival. A: Forest plot derived from pooling 3 cohort studies (random effects model); B: Sensitivity analysis of the model assuming that each study was omitted separately [ln(HR)]; C: Funnel plot with pseudo 95% confidence limits. HR: Hazard ratio; CI: Confidence interval; REML: Restricted maximum likelihood; DES: Drug-eluting stent.
