Table 2 Odds Ratios (ORs) and (95% confidence intervals) for in-hospital mortality; according to the increased percentage of creatinine with respect to basal creatinine*

From: Prognosis and serum creatinine levels in acute renal failure at the time of nephrology consultation: an observational cohort study

  GROUPS OF % CREATININE INCREASE

Creatinine and mortality    
n 323 323  
Incidence of in-hospital mortality, n (%) 73 (22.6) 115 (35.6)  
Odds Ratios    
Crude OR (95% CI) 1.00 (Ref.) 1.89 (1.34–2.68) < 0,001
Age- and sex-adjusted OR (95% CI) 1.00 (Ref.) 1.91 (1.35–2.70) < 0,001
Multivariate-adjusted OR (95% CI) 1.00 (Ref.) 1.81 (1.08–3.03) 0.024
Additionally adjusted for Oncology patients 1.00 (Ref.) 1.85 (1.09–3.14) 0.023
  1. * Creatinine change (%) = [(creatinine at nephrology consultation - Basal creatinine)/Basal creatinine] × 100
  2. Adjusted for age, sex, Liano scoring, Karnofsky scoring, prior food intake, chronic renal failure, diabetes, treatment of acute renal failure, causes of acute renal failure, community-acquired acute renal failure, basal hemoglobin, basal serum albumin, and RIFLE classes.
