MI details for all participants. (A) MI distribution across the sample; (B) correlations between subjective total sleep duration and objective total sleep duration for each MI group. Low MI is shown in blue (overestimators: Q1, MI ≤ −0.19, n = 678), intermediate MI is shown in green (normoestimators: IQR, −0.19 to < 0.08, n = 1350), and high MI is shown in red (underestimators: Q4, MI > 0.08, n = 646). IQR interquartile range, Q1 lowest quartile, Q4 highest quartile, MI misperception index.
