The CRP/PAB ratio outperforms the LRINEC score in early diagnosis of Fournier's gangrene.

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
Background: Fournier's gangrene (FG) is scarce and potentially fatal disease. Although the Laboratory Risk Indicator for Necrotizing Fasciitis (LRINEC) score was established in 2004, its reliability as a diagnostic tool to differentiate between FG and perianal abscess is still debated. The objective of this study was to assess the reliability of the LRINEC score and other relevant inflammatory markers. The diagnostic effectiveness of these inflammatory factors was evaluated and compared. Methods: Retrospective observational study of patients with FG or with perianal abscess. Fifty-two patients with FG and 39 patients with perianal abscess treated in Shenyang Coloproctology Hospital between January 2019 and December 2023 were enrolled in the study. Results: The area under the ROC curve (C-statistic) of a LRINEC score ≥6 for diagnosing FG was 0.736. Inflammatory markers, including C-reactive protein (CRP), procalcitonin (PCT), prealbumin (PAB), neutrophil-to-lymphocyte ratio (NLR), and systemic immune inflammation index (SII), demonstrated better diagnostic ability compared to the LRINEC score. Particularly, the compound inflammatory factor of CRP-to-PAB (CRP/PAB) ratio exhibited superior diagnostic ability compared to other markers (C-statistic: 0.908; Conclusions: The LRINEC score demonstrated only modest discriminative performance in this study. Patients with PAB< 91mg/L and a CRP/PAB≥ 1.52 should undergo careful evaluation for the presence of FG. The elevated CRP/PAB ratio is considered an early indicator for FG, particularly in distinguishing it from deep perianal abscesses. Further investigation is warranted in future studies to support these findings.
