Bland-Altman plots comparing MLSS and workload at AT determined by Dmax (a), ModDmax (b), IAT (c), + 1 mmol/l (d), OBLA4mmol/l, (e), V-slope (f) methods. The horizontal solid line represents the mean difference between the two measures (bias). The horizontal dashed lines represent the limits of agreement (LOA). n = 7 for IAT method and n = 12 for Dmax, ModDmax, + 1 mmol/l, OBLA4mmol/l and V-slope
