Social restriction-induced changes (preSR → inSR) in sleep–wake behavior in the general sample. (a1–c1) Distributions of SDweek, MSFsc, and SJL preSR (black line) and inSR (red line), percent from group total. (a2–c2) Scatterplots of sleep duration, SDweek (hours), corrected mid-sleep time on free days, MSFsc (chronotype, local time), and social jetlag, SJL (hours), preSR (x axis) vs. inSR (y axis). Each dot represents an individual participant, overlapping dots are coded by color intensity. Diagonal line designates no restriction-induced change in parameter. Green—increase/advance, grey—decrease/delay. Black line—LOESS regression lines illustrate the relationship between the parameter values preSR (x-axis) and the smoothed parameter values inSR (y-axis), pointwise 95% confidence intervals are visualized by bands shaded in yellow. Red dot—intersection point between the diagonal and the LOESS line. Yellow cross coordinates—means of MSFsc preSR and inSR; k—slope of the tangent for the LOESS regression line at the point of mean MSFsc preSR. (a3–c3) Boxplots of individual differences (∆, hours) in SDweek, MSFsc and SJL. Positive values—increase in SDweek, delay in MSFsc. Negative values—decrease in SJL. Whiskers—max and min values, box borders—75th and 25th percentiles, line through the box—median, ×marker—mean.
