Cox proportional hazards model estimates of readmission and death of matched-pairs analysis, Clostridium difficile–associated disease (CDAD)*

Variable CDAD case-patients, no. (%) Controls, no. (%) Hazard ratio (95% CI)
Readmitted within 180 d† 148 (51.0) 92 (31.7) 2.17 (1.59–2.95)
Deaths at 180 d‡ 127 (36.0) 107 (30.3) 1.22 (0.92–1.61)
Deaths at 0–60 d‡ 72 (20.4) 75 (21.2) 0.96 (0.54–1.70)
Deaths at 61–180 d‡ 55 (15.6) 32 (9.1) 2.00 (1.47–2.72)

*CI, confidence interval.
†n = 290 matched pairs; 63 matched pairs were excluded because one or both patients in the pair died during the index hospital admission.
