Figure 1. Comparison of manually edited AHI on PSG to HSAT and in-laboratory portable monitor recording.

Figure 1

(A) Bland-Altman plot of manually edited AHI on PSG compared to HSAT (Nox-T3home). (B) Identity plot of manually edited AHI on PSG compared to HSAT (Nox-T3home). (C) Bland Altman plot of manually edited AHI on PSG compared to in-laboratory portable monitor recording (Nox-T3lab). (D) Identity plot of manually edited AHI on PSG compared to (Nox-T3lab). Scoring of hypopneas in all recordings required a ≥ 4% oxygen desaturation event. AHI = apneahypopnea index, CI = confidence interval, HSAT = home sleep apnea testing, Nox-T3 home = home sleep apnea testing using the Nox-T3 device, Nox-T3lab = in-laboratory portable monitor recording using the Nox-T3 device, PSG = polysomnogram.
