Risk factors, microbiological resistance, and prognostic scoring in Fournier's gangrene: a retrospective cohort study.
Article in BMC infectious diseases, 2026. 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
backgroundFournier’s gangrene is a rapidly progressing necrotizing fasciitis of the perineal and genital regions with high mortality. This study aimed to identify prognostic factors and evaluate scoring systems for risk stratification.
methodsA retrospective analysis of 228 Fournier’s gangrene patients was conducted. Baseline data, comorbidities, laboratory findings, microbial cultures, and antimicrobial susceptibility profiles were reviewed. Univariate and Firth’s penalized likelihood logistic regression identified independent mortality predictors. The prognostic value of LRINEC, FGSI, UFGSI, and ACCI scores was assessed via ROC analysis.
resultsMortality was 9.6%. Independent predictors included sepsis (OR = 14.270, P = 0.0008), paraplegia (OR = 18.786, P = 0.0114), and elevated lactate (OR = 1.117, P = 0.0017). Acinetobacter baumannii infection and carbapenem resistance were associated with poor outcomes. UFGSI achieved the best prognostic performance (AUC = 0.933, sensitivity 90.9%, specificity 83.0%).
conclusionGram-negative and mixed infections, particularly those involving Acinetobacter baumannii, represent high-risk subtypes of Fournier’s gangrene associated with increased mortality. Extensive antimicrobial resistance among Gram-negative pathogens underscores the need to revise empirical treatment strategies. Sepsis, paraplegia, and elevated lactate levels independently predict death, while the UFGSI demonstrates superior prognostic accuracy. Early recognition of these risk factors and timely intervention are crucial for improving patient outcomes.
