Analyses are adjusted for age group, sex, race, ethnicity, insurance status, zip code median income, rurality, Elixhauser comorbidities, presence of implantable cardioverter‐defibrillator, listed hospital characteristics, and clustering by hospital‐year. aOR indicates adjusted odds ratio; and SRT septal reduction therapy.
