Table 1.
Table describes the baseline characteristics of the patients (CIN group, n = 31) with an increase of plasma creatinine of greater than or equal to 0.5 mg/dL (or an increase of 25% from baseline) and those of those who did not meet those criteria (Controls group, n = 122). Descriptive data and risk factors of the patients included in the study. Data are presented as percentage or median (minimum, maximum). Previous kidney failure: patients with plasma creatinine levels greater than 1.2 mg/dL (in men) or 0.9 mg/dL (in women) before contrast media administration. BMI: body mass index; CIN: contrast-induced nephropathy; CKD-EPI: Chronic Kidney Disease Epidemiology Collaboration; eGFR: estimated glomerular filtration rate; MDRD-IDMS: Modification of Diet in Renal Disease-Isotope Dilution Mass Spectrometry; n.s. not significant.
