Difference between self-reported MVPA and Freedson MVPA for each quartile of Freedson MVPA. Legend: MVPA = moderate-to-vigorous physical activity; Freedson MVPA = weekly minutes of accelerometer-derived moderate-to-vigorous physical activity ≥1952 counts.min−1; Q1 = first quartile; Q2 = second quartile; Q3 = third quartile; Q4 = fourth quartile. y-axis represent differences between self-reported MVPA and Freedson MVPA, expressed as a percentage; x-axis represent quartiles of Freedson MVPA. Full lines represent median (M) percentage of difference, dotted lines show the 90% nonparametric limits of agreement (LOA), representing 5th and 95th percentiles (P5 and P95): Q1: M = 2689.5; P5 = −99.9 (95% CI for P5: −99.9 - -99.8); P95 = 22271.3 (95% CI for P95: 15800.0 – 39200.0); Q2: M = 799.9; P5 = −99.9 (95% CI for P5: −99.9 - -48.3); P95 = 4177.2 (95% CI for P95: 3203.7 – 5383.9); Q3: M = 515.0; P5 = −46.9 (95% CI for P5: −95.0 – 55.7); P95 = 1597.0 (95% CI for P95: 1360.1 – 1904.5); Q4: M = 128.8; P5 = −45.4 (95% CI for P5: −75.2 - -13.3); P95 = 708.54 (95% CI for P95: 585.7 – 853.5).
