Participants were adults with moderate to severe OSA and intolerant of positive airway pressure therapy.

Baseline median (IQR) HB was 63.4 (47.8-96.6) %min\/h. After 12 months of therapy, the median (IQR) percentage HB reduction was 76.6% (33.1%-90.7%). The posttreatment HB was 21.2 (7.1-53.8) %min\/h for the high HB group and 11.3 (6.1-35.9) %min\/h for the low HB group. In the high HB group, ESS improvement was associated with HB reductions (\u03b2\u2009=\u20091.25; 95% CI, 0.02-2.48), but not with reduced AHI, Arousal Index, or traditional oxygen metrics. In the high HB group (36 responders and 18 nonresponders per Sher-20 criteria), 44 participants (81.5%), including 9 nonresponders, transitioned to low HB after hypoglossal nerve stimulation therapy. In the low HB group, all 36 responders retained their low HB; in addition, 11 of 18 nonresponders (61.1%) showed low HB.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions and Relevance<\/jats:title>\n                    <jats:p>In this secondary analysis of the STAR trial, hypoglossal nerve stimulation therapy was signficantly associated with reduced HB in patients with OSA. Daytime sleepiness improvement correlated with HB reduction but not with AHI or Arousal Index changes. Notably, at least half of nonresponders showed marked HB improvement, which suggests that HB may serve as a complementary physiologic marker to AHI for assessing treatment response.<\/jats:p>\n
