Fig. 1.

Dose–response relationship between step volume, step intensity, and risk of hospitalization. (A) Steps per day and (B) Steps per minute. Hazard ratios (solidline) with 95%CIs (dotted lines) for the most adjusted model (i.e., Model 4). Exposures are modelled in its continuous form and use the median as a reference (5310 for daily steps (A); and 6.7 for steps/min (B)). Darker colors in the lower bars represent a higher sample clustering (top-coded at the 99th percentile). 95%CI = 95% confidence interval.
