CCI indicates Charlson Comorbidity Index; IQR, interquartile range; SAVR, surgical aortic valve replacement; TAVR, transcatheter aortic valve replacement.

Statistical significance.

Median household income for each patient's ZIP code was characterized into quartiles, each year.

Hospital size was based on the number of short‐term acute care hospital beds; cut points were chosen for each region and location combination so that approximately one third of hospitals would appear in each category.
