Intravenous Immunoglobulin Therapy for Pyoderma Gangrenosum: A Multicenter Retrospective Analysis in 81 Patients.
Article in American journal of clinical dermatology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
backgroundPyoderma gangrenosum (PG) is rare neutrophil skin disease causing painful, progressively enlarging ulcers. Among the treatment options, intravenous immunoglobulin (IVIG) is a therapy of first choice for paraneoplastic PG. Otherwise, it is used in therapy-refractory courses.
objectiveTo assess the efficacy and safety of IVIG therapy in patients with PG.
methodsA retrospective chart review for patients in five dermatologic wound centres in Germany was performed.
resultsOverall, 81 patients were included. IVIG was used as adjunct therapy with (methyl-) prednisolone and/or a steroid sparing therapy in 77 (95.1%) cases. Response to treatment (combined complete and partial, defined as tendency to heal and cessation of lesion progression, respectively) was 49.3% 1 month after initiation of IVIG. In total 18.8% had a complete response after 6 months. Statistically significantly higher response rates were observed in patients with diabetes mellitus and thyroid disease [odds ratio (OR) 3.49, confidence interval (CI) 1.13-10.80 and OR 6.64, CI 1.01-43.57, respectively]. Patients with solid malignancy tended to have better response (OR 4.36, CI 0.79-23.91). A higher IVIG dose was also associated with a tendency towards better response rates (OR 2.70, CI 0.84-8.63). In total, 1 (1.2%) severe adverse event (myocardial infarction with consequent death) was observed as well as three moderate adverse events, with two thromboembolic events (2.5%) and one acute kidney injury (1.2%). Other adverse events were mild or unlikely to be associated with IVIG therapy, with 14 events in 10 patients overall (12.3%).
conclusionsThis multicentre retrospective study shows the important role of adjunctive IVIG therapy in patients with PG with recalcitrant courses. Identifying subgroups with a higher probability of response could improve future response rates and save patients from ineffective treatment and potential adverse events.
