2. Figure 1
Kaplan-Meier curves for all-cause and cardiovascular (CV) death according to quartiles (Q) of maximal quadriceps isometric strength. The cut-off values defining the quadriceps isometric strength quartiles were ≤35.0% body weight (BW), 35.1%-44.8% BW, 44.9%-55.9% BW, and ≥56.0% BW for Q1 to Q4, respectively.

All-cause and cardiovascular death risk across maximal quadriceps isometric strength quartiles (Q). ∗Adjusted for age, body mass index, previous heart failure, and previous stroke and/or transient ischemic attack for all-cause death, and age, body mass index, coronary artery bypass grafting, previous heart failure, previous stroke and/or transient ischemic attack, end-stage renal disease, and coronary artery multivessel disease for cardiovascular (CV) death. % BW = percentage of body weight; CI = confidence interval; HR = hazard ratio; QIS = quadriceps isometric strength.

Forest plot of hazard ratio for association of quadriceps isometric strength with all-cause and cardiovascular (CV) mortality. ∗Adjusted for age, body mass index, previous heart failure, and previous stroke and/or transient ischemic attack for all-cause death, and age, body mass index, coronary artery bypass grafting, previous heart failure, previous stroke and/or transient ischemic attack, end-stage renal disease, and coronary artery multivessel disease for CV death. BMI = body mass index; % BW = percentage of body weight; HR = hazard ratio; LVEF = left ventricular ejection fraction; QIS = quadriceps isometric strength.
