was 1.60 (95% confidence interval [CI], 1.02-2.51), P = .04. 2. Of those subjects who received a PPI and vancomycin alone, the relapse rate was 28.0% (7/25), compared to 10.3% (8/78) in those who received vancomycin alone and no PPI. The unadjusted OR was 3.40 (95% CI, 1.0910.63), P = .05. 3. Of those who received any treatment (metronidazole or vancomycin or both) and a PPI, the relapse rate was 33.8% (68/201), compared to 21.7% (123/568) for those who did not receive a PPI. The unadjusted OR was 1.85 (95% CI, 1.30-2.64), P<.01. 4. Of those patients who received both metronidazole and vancomycin as well as a PPI, the relapse rate was 42.9% (21/49), compared to 26.2% (37/141) for those who received both agents but not a PPI. The unadjusted OR was 2.11 (95% CI, 1.07-4.16), P = .03.
