a Factor analysis: Display of the 5-factor model results, labeled as timing, efficiency, duration, rhythmicity, and regularity. Numbers indicate factor loadings; purple dashed arrows denote negative correlations between the latent factor and its corresponding original variables. AD all days average, WD weekdays average, WE weekend days average, WASO wake after sleep onset, (sd) standard deviation, IV intra-daily variability, RA relative amplitude, IS inter-daily stability. b Latent profile analysis: Identification of the optimal model with two profiles, based on the best integrated completed likelihood values. The x-axis shows the five factors obtained from the factor analysis, and the y-axis shows the standardized factor scores. Source data are provided as a Source Data file.
