Relationship between CDI history in the previous 6 months and occurrence of rCDI in placebo-treated participants receiving metronidazole or vancomycin. The relationship between CDI history in the previous 6 months and occurrence of rCDI in placebo-treated participants with ICC (n = 621) is represented by the dotted trend line. The difference in the percentage of participants in the metronidazole and vancomycin subgroups with a history of CDI in the previous 6 months is represented by the distance between the black (metronidazole) and gray (vancomycin) reference lines. Abbreviations: CDI, Clostridioides difficile infection; ICC, initial clinical cure; rCDI, recurrent C. difficile infection.
