Investigation of self-reported chronic urticaria among adults in grasslands of northern China.
Article in Medicine, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
The clinical epidemiological characteristics of chronic urticaria (CU) in different populations were not completely consistent, and the epidemiological characteristics of CU were very complex. At present, there were some patient-based studies on CU, but few natural population-based studied in the world.This study aimed to analysis the prevalence of self-reported CU among adults in grasslands of northern China and its closely related factors.A multistage and proportionately stratified random sampling with a field interviewer-administered survey study was performed together with skin prick tests (SPT) and measurements of the daily pollen count.A total of 3406 subjects completed the study. The prevalence of self-reported CU was 5.61% (n = 191), which was higher in women than that of men (6.91% vs 4.08%, X = 12.785, P < .001). Seasonal or seasonal aggravation CU accounted for 110 (57.59%) patients. Pollen dispersal season was basically consistent with the peak season of CU, but there was no significant difference in the positive rate of pollen SPT between CU with seasonal or seasonal aggravation symptom and CU with free of symptom (X = 0.425, P = .51), as well as between CU with seasonal or seasonal aggravation symptom and perennial CU (X = 0.439, P = .51). Eczema (odds ratio [OR] = 2.807, P < .001), chronic diarrhea (OR = 2.486, P < .01), food allergy history (OR = 1.890, P < .01), history of family allergy (OR = 1.800, P < .001), and conjunctivitis (OR = 1.749, P < .01) were closely related to CU.This investigation provided the factors closely related to CU, and provided certain ideas for further research on the etiology and prevention of CU.
