The utility of biopsy in pyoderma gangrenosum: a retrospective cohort study.
Article in Skin health and disease, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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: Pyoderma gangrenosum (PG) is a rare skin condition characterized by chronic, painful ulcerations. It is considered a diagnosis of exclusion, often resulting in diagnostic delay. Histological results in PG, even when biopsied despite a risk of pathergy, are nonspecific. Objectives: To examine retrospectively the utility of biopsies in the diagnosis of 58 patients treated for PG. Methods: Medical records were reviewed to compare biopsy results versus the efficacy of diagnostic rating systems (Delphi, Su, PARACELSUS). Results: Among 58 patients, 26 (45%) underwent biopsies, with only 10 (38%) contributing to a PG diagnosis. As a single-centre and retrospective study, documentation style and sample size limit generalizability. Conclusions: Given risk of pathergy, nonspecific histopathological findings and low sensitivity, in our opinion, based on this small sample size, biopsies have limited diagnostic value for PG.
