Changes in activity features throughout the pre- and postoperative period. Differences in weekly feature means relative to the feature mean of a baseline week (12 weeks prior to the operation) across patients. Error bars correspond to the standard deviation of differences across patients. Weeks that are significantly different from baseline are denoted with triangles, with colors that correspond to different significance levels (gray: p < 0.05; yellow: p < 0.00217; orange: p < 0.00036), and directionality indicating an increase or a decrease relative to baseline.
