(a)–(c) Bland-Altman plots of AHI comparisons. (a) HST-auto vs. HST-tech, (b) HST-auto vs. PSG, and (c) HST-tech vs. PSG. Blue solid lines are a zero reference, red solid lines are the mean difference, dashed red lines represent the ±2 standard deviations from the mean, and dashed green line represents the ±3 standard deviations from the mean (for image resolution, given ranges, not all standard deviation lines were graphically presented).
