Results of the Cox proportional hazard models of the walking speed for outcomes

OutcomesNo. of events/casesHR (95% CI)P value
Combined events (per 0.1 m/s increase)429/1391 (30.8%)0.951 (0.912–0.992)0.035
All-cause death (per 0.1 m/s increase)134/1391 (9.6%)0.924 (0.853–0.998)0.048
OutcomesNo. of events/casesHR (95% CI)P value
Combined events (per 0.1 m/s increase)429/1391 (30.8%)0.951 (0.912–0.992)0.035
All-cause death (per 0.1 m/s increase)134/1391 (9.6%)0.924 (0.853–0.998)0.048

Adjustment variables used for combined events and all-cause death were age; sex; body mass index; New York Heart Association class III/IV; systolic blood pressure; left ventricular ejection fraction; current smoking status; history of heart failure (whether or not a history of hospitalization); hypertension, diabetes, coronary artery disease, chronic obstructive pulmonary disease, atrial fibrillation, and stroke; eGFR; haemoglobin; serum sodium level; serum albumin; log-transformed BNP; prescription of angiotensin-converting enzyme inhibitor or angiotensin receptor blocker, beta-blocker, and mineralocorticoid receptor antagonist at admission; and physical activity level before admission.

CI, confidence interval; HR, hazard ratio.
