Sociodemographic factors, military service, lifestyle, and cardiovascular disease risk factors in twins with and without obstructive sleep apnea.

Myocardial perfusion imaging data in twins with and without obstructive sleep apnea.
Fig 2.
Association of a total severity score ≥100, a measure of abnormal myocardial perfusion obtained using positron emission tomography myocardial perfusion imaging, with indicators of obstructive sleep apnea classified in tertiles of their distribution, including the Apnea/Hypopnea Index (AHI), the Respiratory Disturbance Index (RDI), the oxygen desaturation index (ODI), and the cumulative proportion (%) of sleep spent with oxygen saturation (SaO2) < 90%.
P values test the difference between first and third tertile.
Table 3.
Multivariable analysis of the relationship between the Apnea-Hypopnea Index (AHI), both as a dichotomous variable (AHI ≥15) and as a continuous variable, and total severity score ≥100, in the overall sample with twins treated as individuals.
Table 4.
Within-pair and between-pair relationships between the Apnea-Hypopnea Index (AHI) as a continuous variable and total severity score ≥100, in twins discordant for AHI (at least 5-point difference).
The pairwise analysis is also shown for AHI status as a categorical variable.
