From: Stationary gaze entropy predicts lane departure events in sleep-deprived drivers
Mean and standard errors across driving duration by condition (red = sleep-deprived, green = rested) with curvilinear fits for blink rate -Top Left, sleep-deprived: (ŷ = 30.727 + 1.964x − 0.033x2 + 0.0002x3), rested: (ŷ = 41.780 + 0.277x − 0.002x2); blink duration-Bottom Left, sleep-deprived: (ŷ = 168.606 + 2.332x − 0.036x2 + 0.0002x3), rested: (ŷ = 136.400 + 2.332x − 0.030x2 + 0.0001x3), fixation rate - Top Right, sleep-deprived: (ŷ = 55.829 − 1.090x − 0.016x2 − 0.0001x3), rested: (ŷ = 63.081 + 0.077x); and saccade amplitude - Bottom Right, sleep-deprived: (ŷ = 33.462 + 0.769x − 0.014x2 − 0.0001x3), rested: (ŷ = 14.878 + 0.723x − 0.012x2 + 0.0001x3).
