Figure 2 Multivariable Cox Proportional Hazards Survival Plots for Patients With M-NSA Versus Untreated OSA
Multivariable Cox proportional hazards plots showing worse survival of heart failure patients with untreated obstructive sleep apnea (OSA) than in those with mild to no sleep apnea (M-NSA) (hazard ratio = 2.81, p = 0.029) after adjusting for significant confounders (left ventricular ejection fraction, New York Heart Association functional class, and age per Table 3). The adjusted survival curves are shown at the average values of these confounders.
