BRD2 and obstructive sleep apnea syndrome: Multivariable analysis showed that OSA (OR, 2.72; 95% CI, 1.35–5.49; p = 0.005), White race (OR, 0.44; 95% CI, 0.19–0.99; p = 0.048), and NAT chemo‐radiation (OR, 0.39; 95% CI, 0.19–0.79; p = 0.008) were independently predictive of pathological response (Figure 1C and Figure S1B).
