Association between sedentary time and mortality across levels of frailty

Kaplan–Meier Curves stratified by frailty index score and whether participants were physically active or inactive (as determined by objective measurement). *For the physically active participants, the groups with frailty index score ≤ 0.1 and 0.1 < frailty index score ≤ 0.2 were merged, as were the groups with 0.2 < frailty index score ≤ 0.3 and frailty index score > 0.3, because of small sample sizes.
