Acquired Angioedema Associated With Systemic Lupus Erythematosus Presenting as Acute Abdomen: A Case Report.
Article in Journal of general and family medicine, 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
Acquired angioedema (AAE) due to C1 inhibitor deficiency can present as acute abdomen. A 24-year-old woman developed severe abdominal pain and bowel wall edema initially suggestive of hereditary angioedema, but genetic testing excluded it. She later manifested fever, arthritis, rash, and serological abnormalities consistent with systemic lupus erythematosus (SLE). SLE-associated AAE was diagnosed, and immunosuppressive therapy led to clinical and biochemical improvement. This case highlights the importance of considering AAE in patients with unexplained abdominal pain and hypocomplementemia to avoid misdiagnosis and unnecessary surgical intervention.
