Adjusted mean activity counts per minute across the hours of the day, according to the time of sunset. cpm = counts per minute. Analysis based on 158,784 measurement days from 23,188 children from 15 studies in 9 countries. Analyses adjust for study population, age, sex, day of the week, weight status and the six weather variables, with a reference group of 09:00 on days with sunset before 18:00. Hours are rounded down, e.g. ‘18’ covers ‘18:00–18:59’. Confidence intervals not presented as they are generally too narrow to be clearly visible: Additional file 1: Figure A1 includes a version of this graph with confidence intervals.
