Figures & data

Table 1. Baseline characteristics (n = 69).

Figure 1. Scatterplot of sedentary time against moderate-vigorous intensity physical activity (MVPA), stratified by sedentariness (sedentary time ≥70% of waking wear time) and physical activity levels (MVPA ≥30 min/day). Of the 69 participants, 57% were classified as “sedentary” and 43% as “non-sedentary”; 41% were classified as “inactive” and 59% as “active”. Solid circles: 6MWD <80% predicted; blank circles: 6MWD ≥80% predicted.
