FIGURE 2

Mean waveforms and actograms for early (E-types, in yellow; n = 20% of total subjects), neither (N-types, in dotted black; n = 60% of total subjects), and late-types (L-types, in blue; n = 20% of total subjects) for: (A) wrist temperature (WT; total subjects = 159), (B) activity (A; total subjects = 159), and (C) body position (P; total subjects = 159). Waveform data are expressed as mean ± SEM. WT actogram corresponds to the third tercile values, while activity and body position actograms correspond to the first tercile values (values corresponding to the rest phase).
