Post-caesarean pyoderma gangrenosum mimicking surgical site infection: a diagnostic pitfall in the postpartum period.
Article in Journal of surgical case reports, 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
Pyoderma gangrenosum (PG) is a rare neutrophilic dermatosis that may occur after surgery and mimic wound infection. We report the case of a 30-year-old woman who developed painful progressive ulceration 7 days after caesarean section. Initial treatment with broad-spectrum antibiotics for presumed surgical site infection was ineffective. Clinical examination showed a large hypogastric ulcer with an erythematous base and undermined inflammatory borders. Histopathological examination of a biopsy taken from the ulcer edge demonstrated a dense dermal neutrophilic infiltrate, supporting the diagnosis of PG. Oral prednisolone at 1 mg/kg/day was started, with progressive improvement and complete re-epithelialization after 4 months. This case highlights the importance of considering PG in postoperative wounds that worsen despite adequate antimicrobial treatment, in order to avoid unnecessary surgical procedures and initiate timely immunosuppressive therapy.
