Comparison of Culturing Methods of Primary Vaginal Fibroblasts.
Article in Urogynecology (Philadelphia, Pa.), 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the 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.
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
importanceVaginal fibroblast function is altered in people with pelvic organ prolapse. Thus, it is important to study vaginal fibroblasts to better understand the pathophysiology of prolapse.
objectiveThis study aimed to compare 3 culturing methods of primary vaginal fibroblasts. STUDY
designThis was an in vitro study. Patients who were undergoing surgery for vaginal prolapse were recruited. Excess vaginal epithelial tissue that would have otherwise been discarded was collected. The vaginal fibroblasts from each participant were cultured via (1) 3-hour digest, (2) coverslip, and (3) gelatin-coat methods. Differences in the efficiency of cell isolation, expression of known fibroblast-associated genes, and cellular function were compared between the 3 methods using one-way analysis of variance and Tukey test for post hoc pairwise comparisons ( P < 0.05).
resultsFive patients with pelvic organ prolapse were recruited. Fibroblasts cultured via the 3-hour digest method became confluent within 3-5 days in a 100-mm dish compared to 2-3 weeks in a 6-well dish for the coverslip and gelatin-coat methods. Cells from all culture methods expressed similar amounts of vimentin and α smooth muscle actin. There were no significant differences in morphology; gene expression levels of MMP1 , MMP2 , ACTA2 , COL1A1 , COL3A1 , and LOXL1 on qPCR; cell viability; proliferation; and migration between the 3 culturing methods.
conclusionCulturing primary vaginal fibroblasts via the 3-hour digest, coverslip, and gelatin-coat methods similarly resulted in reliable primary vaginal fibroblast growth and function.
