Fig. 1: Predicted survival curves from the fully adjusted Cox proportional hazards models.
From: Circadian disturbances and frailty risk in older adults

The predicted probabilities of being not frail for two representative participants with circadian metrics (a) amplitude, (b) variation of cycle length, (c) IS, (d) IV, or (e) M10 at the 10th (red lines) and 90th percentiles (blue lines). IS interdaily stability, IV intradaily variability, M10 the average activity during the most active 10-h period. Source data are provided as a Source Data file.
