Comparison of performance of Simulation 1 and Simulation 2 overall and by group. RMSE: root mean square error; LOA: limits of agreement; MAE (SD): mean absolute error and standard deviation; C: control; ST + L: 8 h afternoon-evening sleep timing and night shift bright light; ST: 8 h afternoon-evening sleep timing; and SA: ad lib afternoon-evening sleep timing.
