Figure 3. Defining Characteristics of Drive-Dependent v. Classic OSA During Events.

Figure 3.

Patients visually classified as drive-dependent (N=30) exhibited a higher flow-drive correlation during events (A) and have greater reduction in drive (B) than those classified as classic (N=20), supporting the visual scoring. Variables were quantified from ensemble-average events. The flow-drive correlation (R) and reduction in drive (Δdrive/Δflow) discriminated between groups (see dashed line drawn from a regression model). (D) OSA severity was similar between groups.
