Non-inferiority of metronidazole to vancomycin in the treatment of first episode non-severe Clostridioides difficile infection: a single center retrospective cohort study.
Article in Infection, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectivesWe sought to assess the effectiveness of oral vancomycin compared to metronidazole on recurrence and mortality among hospitalized patients with non-severe Clostridioides difficile infection (CDI).
methodsA single center retrospective cohort study was conducted, including adult patients hospitalized between 2015 and 2020 with a first episode of non-severe CDI, treated with metronidazole or vancomycin as monotherapy for at least 10 days. We assessed recurrence of CDI requiring hospitalization (primary outcome) and all-cause mortality up to 8 weeks, post discharge.
resultsOverall, 160 patients were treated with vancomycin and 149 treated with metronidazole. Re-hospitalization within 8 weeks due to CDI occurred in 10 (6.2%) patients in the vancomycin group, and 13 (8.7%) in the metronidazole group (P value = 0.407). Eight-week mortality occurred in 39 patients (26.2%) in the metronidazole group and 46 patients (28.8%) in the vancomycin group (P value = 0.61). After adjusting for age, gender, Ischemic heart disease, white blood cell count, neutrophile count and CRP, there was no significant difference between the two treatments (Re-hospitalization in 8 weeks due to CDI P = 0.5059; In-hospital death P = 0.7950; 4-week mortality P = 0.2988; 8-week mortality P = 0.8237).
conclusionThere is no benefit of using vancomycin compared to metronidazole concerning recurrence rate requiring hospitalization, in-hospital and up to 4- and 8-week mortality rate in non-severe first episode of CDI.
