Figure 1. Comparisons of Beddit and PSG estimates.

Figure 1

Comparisons of Beddit and PSG estimates of bedtime (ICC > 0.99 for Beddit 3.5) (A), SE% (ICC = 0.98 for Beddit 3.5, ICC = 0.26 for Beddit 3.0) (B), SOL (ICC = 0.92 for Beddit 3.5, ICC = 0.02 for Beddit 3.0) (C), and WASO (ICC = 0.92 for Beddit 3.5, ICC = –0.02 for Beddit 3.0) (D). The diagonal lines indicate perfect agreement between Beddit and PSG. ICC = intraclass correlation coefficient, PSG = polysomnography, SE% = sleep efficiency, SOL = sleep onset latency, WASO = wake after sleep onset.
