Restricted cubic spline regression model between KCL (a) and FSI (b) score and risk of all-cause mortality. The Kihon Checklist (KCL) and Frailty Screening Index (FSI) received a point by every problem with activity or function, and the higher the total score, the greater the difficulty in daily functioning (high frailty). Solid lines represent hazard ratios, and dashed lines represent 95% confidence intervals (CI), and the hazard ratio based on 0 point of both KCL and FSI as reference was calculated. We estimated that p < 0.05 when the 95% CI of the hazard ratio exceeded 1.00, and p ≥ 0.05 when the 95% CI of the hazard ratio did not exceed 1.00. The adjustment factors are age, sex, population density, family structure, economic status, educational attainment, smoking status, alcohol consumption status, sleep time, medication use, and number of chronic diseases.
