Fig. 2. Forest plots depicting hazard ratios (HRs) for all-cause mortality in the (A) underweight, (B) overweight, and (C) obese groups in reference to the normal-weight group. The numbers of patients and events for each body mass index (BMI) category were not specified in the study by Conway et al.16 The data for each trial are presented in the upper parts of the respective figures, while the pooled data are described in the lower parts. A random-effects model was used to calculate the pooled HRs and 95% confidence intervals (CIs). Statistical heterogeneity with a P-value was evaluated using I2 and Q-statistics. *Patients with BMI 30–35 kg/m2; Patients with BMI > 35 kg/m2.
