Chronic inducible urticaria: confirmation through challenge tests and response to treatment.
Article in Einstein (Sao Paulo, Brazil), 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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 To evaluate the positivity of challenge tests of patients suspected of chronic inducible urticaria and the response to treatment. Methods A retrospective study of electronic medical records of patients suspected of chronic inducible urticaria. All patients were submitted to challenge tests with triggering stimuli, according to the clinical history and, subsequently, the response to drug treatment was evaluated. Results A total of 191 patients with suspected chronic inducible urticaria were included. It was confirmed in 118 patients and 122 positive tests (4 patients with 2 different positive tests). Most had dermographic urticaria (70.3%), followed by cholinergic urticaria (17.8%). Regarding treatment, 28% responded to antihistamine in licensed doses, 34.7% with increased doses, 9.3% responded to the addition of another medication. The concomitance of chronic inducible urticaria and chronic spontaneous urticaria was found in 35.3% of patients, being more frequent in females, with longer time to control symptoms and higher frequency of cholinergic urticaria. Conclusion The confirmation of chronic inducible urticaria in patients with this suspicion, after challenge tests, was high. There was a good response to antihistamine. In the concomitance of chronic spontaneous urticaria, longer time to control symptoms and higher frequency of cholinergic urticaria were observed.
