Model 1 adjusted for none
Model 2 adjusted for age (except NRS-2002), gender, diabetes, average SBP, eGFR, LVEF, hemoglobin, C-reactive protein, the volume of contrast agent consumption, the type of contrast agent
Model 3 additionally adjusted for pre-procedure medication, including statin, furosemide, and dopamine
The NRS-2002 scores already took age into account, and thus age was not adjusted in the multivariable model. The complete multivariable linear regression model (including covariates) is presented in Table S2–3. CI indicates confidence interval. Other abbreviations refer to Table 1
