  1. aAPACHE II score, Acute Physiology and Chronic Health Evaluation II score; CRP, C-reactive protein; FT3, free triiodothyronine; FT4, free thyroxine; NT-proBNP, N-terminal pro-brain natriuretic peptide; rT3, reverse triiodothyronine; TSH, thyroid-stimulating-hormone; TT3, total triiodothyronine; TT4, total thyroxine; T3/rT3, the ratio of rT3 to T3. Standard β value was calculated using the semistandardization method (X standardization). Odds ratios are shown as standardized OR per 1 SD. Log variable is the logarithm of the variable.
