Figure 4.

Post‐TAVR length of stay and 1‐year all‐cause readmission risk. (A) Unadjusted and (B) adjusted models are depicted with length of stay modeled as a restricted cubic spline with knots at 3, 6, and 13 days. All models accounted for correlation within hospitals. Risk adjustment included age, sex, frailty, left ventricular ejection fraction, peripheral vascular disease, cerebral vascular disease, chronic obstructive pulmonary disease, serum creatinine, recent heart failure hospitalization within 90 days, year of TAVR, and warfarin use within 90 days of discharge. HR indicates hazard ratio; TAVR, transcatheter aortic valve replacement.
