Impact of surgical field disinfection on vaginal microbiome in transvaginal urogynecological surgery: a prospective cohort study.
Article in Antimicrobial resistance and infection control, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT04301401 (Assessment of Changes in Vaginal Microbiota Profiles Before and After Vaginal Urogynecologic Surgery), which is not on this map. Not yet cited in PubMed.
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.

Abstract
backgroundThe study aimed to assess the effects of vaginal disinfection and sterile draping on the composition and dynamics of the vaginal microbiota during vaginal surgery.
methodsA prospective cohort study was conducted involving post-menopausal patients undergoing vaginal urogynecological surgery. The vaginal microbiota was assessed by partial 16 S rRNA gene sequencing at three time points: before disinfection (V1); immediately after disinfection and sterile draping (V2); and one-hour post-disinfection (V3).
findingsIn a cohort of 54 postmenopausal women (median age: 69.2 ± 7.6 years), with a mean operative time of 92.89 ± 45.92 min, native tissue prolapse repair was the most common urogynecological vaginal procedure performed (n = 47, 87%). The vaginal microbiota diversity was significantly increased after disinfection associated with reduced abundance of Lactobacillus and Bifidobacterium and increased Pseudomonas (p < 0.0001). Community state type (CST) I prevalence decreased notably from 20% at V1 to 6% at V3, primarily due to the disappearance of CST I-A, while CST IV prevalence rose from 31 to 44%, which was mainly secondary to an increase in CST IV-C (from 20 to 33%).
conclusionsThese findings highlight the impact of povidone-iodine on vaginal microbiota composition during vaginal urogynecological surgery. Disinfection significantly increased vaginal bacterial diversity and reducing Lactobacillus abundance. This observation requires further exploration in the context of development of optimized disinfection protocols aimed at preserving vaginal health during and after surgery.
