Clinical and aetiologic profile of patients with chronic urticaria at the outpatient clinic of a tertiary hospital in Lagos, Nigeria: a cross-sectional observational study.
Observational study in The Pan African medical journal, 2021. 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
Chronic urticaria is a condition characterized by recurrent wheals associated with itching lasting longer than six weeks. The condition tends to run a chronic course with significant morbidity. Several factors have been explored in the cause, yet the aetiology is still uncertain. We documented the clinical profile and assessed the possible aetiologic factors in patients with chronic urticaria. Clinical profile of sixty consecutive patients with chronic spontaneous urticaria was assessed with possible precipitants identified using a structured questionnaire. The complete blood count with erythrocyte sedimentation rate, antithyroid peroxidase (antiTPO), hepatitis B surface antigen (HBsAg), antihepatitis C virus screening (AntiHCV), stool for ova and parasites and helicobacter pylori were carried out. Controls without a history of urticaria were recruited in a 1: 1 ratio for stool for parasites and H. pylori because of the high prevalence rates reported in this environment. Data analysis was carried out with Statistical Packages for Social Sciences (SPSS) version 22. Sixty patients with chronic urticaria and sixty age and sex matched controls were enrolled in the study. Females presented more often with urticaria with a M: F ratio of 1: 2.5. The mean age of onset of urticaria was in the third decade of life. Precipitants were identified in close to a third of patients. The investigated antigenic aetiology was not found to play a role. The presentation and clinical profile of patients in this environment is similar to previously documented studies. History still remains the cornerstone of management as precipitants and triggers may be identified. Management of patients should therefore be individualized.
