Forest plots of the CVD mortality risk according to the frailty status. A The pooled HR and 95% CI of the CVD mortality in the frail group compared with the robust group; B The pooled HR and 95% CI of the CVD mortality in the prefrail group compared with the robust group; C The pooled HR of the CVD mortality risk per 0.1 increase in the frailty index score. CI = confidence interval, CVD = cardiovascular disease, HR = hazard ratio
