Bland-Altman plots comparing self-report and actigraphy measures of sleep. Bland-Altman plot of differences (y-axis) between self-report sleep (PSQI) and actigraphy measured sleep vs. the mean of the two measurements (x-axis). Bias is represented by the red dashed line (), while the upper and lower limits of agreement (LOA) are represented by the black dashed line (). a. Agreement between the PSQI sleep duration and Actiware summary statistics TIB (P ≤ 0.001). b. Agreement between the PSQI sleep duration and WORK-A major interval TIB (P = 0.006). c. Agreement between the Actiware summary statistics TIB and WORK-A major TIB (P ≤ 0.001). d. Agreement between the PSQI reported bedtime and WORK-A major interval median bedtime (P = 0.21). e. Agreement between the PSQI reported waketime and WORK-A major interval median waketime (P = 0.68)
