Fig. 2: Estimated percentage of baseline steps for the first two week after discharge.

The yellow line represents the remote perioperative telemonitoring care arm, and the blue line represents the surgeon only perioperative care arm. Estimated percentage were obtained from mixed effect model to predict the recovery percentage of baseline step at each follow-up day, using time period as an independent variable, subject as a random effect, treatment, age, sex and residential setting as fixed-factors and study arm-by-time period interaction term as the hypothesis variable testing the slope differences over time between study arms. Error bars represent 95% CI of the estimates.
