Alternative indicators and multidimensional phenotypes, such as nocturnal hypoxic burden and novel oxygen saturation metrics, more accurately assess sleep apnea severity and cardiovascular risk than the traditional apnea-hypopnea index (AHI) alone.
The claim states that alternative metrics to the AHI effectively diagnose sleep apnea severity. Papers 5, 6, and 9 specifically evaluate alternative indicators—such as hypoxic burden, SBII, and pRED_3p—and establish that these alternative parameters provide superior or complementary efficacy in evaluating sleep apnea severity and risk stratification compared to relying on the AHI alone. No papers refute this assertion. Thus, the balance of evidence strongly supports the claim.
