Mortality assessed by the Hospital Frailty Risk Score. Patients with intermediate and high risk (HFRS ≥ 5) have significantly higher odds of mortality (OR: 1.98; CI 1.89–2.07) compared to patients with low risk of frailty (HFRS < 5). This analysis was statistically homogeneous (I2 = 0.0%, p = 0.583). OR: odds ratio; CI: confidence interval. p < 0.1 was considered significant
