Risk reclassification with the addition of FT3 level to a risk model based on LGE and LVEF for all‐cause mortality

Abbreviations: FT3, free triiodothyronine; LGE, late gadolinium enhancement; LVEF, left ventricular ejection fraction.

Values are the number of patients in corresponding risk category (0%–10%, 10%–20%, 20%–30%, and ≥30%) according to the risk model based on LGE and LVEF and the risk model based on LGE plus FT3 and LVEF for all‐cause mortality.
