Angiotensin-converting enzyme inhibitor-induced angioedema: Proposal for a diagnostic score.
Article in The World Allergy Organization journal, 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
Objective: Angiotensin-converting enzyme inhibitor (ACEI)-induced angioedema (AE-ACEI) may be life-threatening, and the treatment should therefore be discontinued. However, patients taking ACEI may also have mast cell-mediated angioedema (AE-MC). Differentiating between AE-ACEI and AE-MC in patients taking ACEI is sometimes difficult. We propose to identify the factors associated with the diagnosis of AE-ACEI in patients. Materials and methods: A multicenter retrospective study was carried out at Grenoble Alpes University Hospital and University Hospital of La Réunion. All patients referred for suspected diagnosis of AE-ACEI were included in the study between January 2019 and January 2022. The final diagnosis was made by the expert physician after a minimum follow-up of 1 year and after a biological work-up ruling other bradykinin-mediated angioedema. Results: A total of 93 patients were analyzed, 49 with a final diagnosis of AE-ACEI and 44 with a diagnosis of AE-MC. Multivariate analysis identified 4 factors associated with the final diagnosis of AE-ACEI: number of AE between the introduction of ACEI and the consultation ≤3 (OR: 7.93 [1.60-50.7], p = 0.017) (1 point), duration of AE strictly greater than 24 h regardless of the treatments administered (OR: 8.41[2.07-44.5], p < 0.01) (1 point), hospitalization in intensive care unit (OR: 7.14[1.19-50.0], p = 0.045) (1 point) and no recurrence of AE after stopping ACEI, regardless of the delay (OR: 16.7[3.37-125], p < 0.01) (2 points).This five-point diagnostic score (AUC: 0.85 [0.75-0.95]) identifies patients with a low probability of AE-ACEI when the score is 0-2 (sensitivity: 0.93, specificity: 0.35) and a high probability when it is between 4 and 5 (sensitivity: 0.53, specificity: 0.97). Conclusion: After a consultation in an angioedema expert center, the diagnosis of AE-ACEI has been excluded in almost half the patients. We identified a five-point score that could help in the diagnosis of AE-ACEI and in the decision to contraindicate the use of ACE inhibitors for life.
