A: average (90% prediction interval) HR during daytime (blue). Average 95% CI nighttime HR (red). Reference values (10th– 90th percentile of HR per age year) are displayed in green. B: Average HR (95% CI) per hour of the day. C: estimated relationship between HR and step count for ages 2, 8, 12 and 16. A limited amount of age years is shown for readability.
