Risk of time to first of VAD placement, cardiac transplantation or all-cause mortality by continuous measures thyroid function test individually

Test Hazard ratio 95%CI p-value
TSH per 1 mIU/L 1.03 1.02–1.04 <0.001
FT4 per 0.1 ng/dL 1.12 1.06–1.17 <0.001
TT3 per 10 ng/dL 0.85 0.80–0.90 <0.001

VAD, ventricular assist device; TSH, thyroid stimulating hormone; FT4, free thyroxine; TT3, total triiodothyronine

Cox-proportional hazard models adjusted for age, sex, race, BMI, ischemic etiology, amiodarone use, and levothyroxine use. N=1294 for TSH analyses, 1291 for FT4 analyses, and 1290 for TT3 analyses.
