Risk factors of chronic urticaria among nurses with insomnia: A nationwide population-based study.
Observational study in Medicine, 2019. 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
Chronic urticaria has a high economic burden and reduces patient's quality of life. Nurses experience insomnia because of their shifting work, especially if they work night shifts and 3-shift rotational schedules. This study aimed to examine whether insomnia is a risk factor of chronic urticaria in nurses.Data were obtained from the Registry for Medical Personnel, which contains all registered medical staff between 2007 and 2008. All study subjects were divided into those with insomnia and without insomnia. The primary exposure of interest was chronic urticaria. In addition, potential comorbidities including diabetes mellitus, hypertension, hyperlipidemia, anxiety, and depression were estimated.A total of 103,242 registered nurses between 2007 and 2008 were enrolled. Around 97,899 (94.8%) nurses did not have insomnia, and 5343 (5.2%) had insomnia. The proportion of chronic urticaria in nurses with insomnia was significantly higher than those without (0.92% vs 0.50%, P < .0001). The odds ratio of chronic urticaria in nurses with insomnia was 1.67 (95% confidence interval: 1.22-2.29, P = 0.0014) compared to those without insomnia after adjusting for age, sex, hospital level, and comorbidities.The risk of chronic urticaria was higher in nurses with insomnia than in those without insomnia. The relationship between insomnia and chronic urticaria might not be a direct causal association. Other contributing factors of insomnia include different perceptions of stress from night shift work, stress coping and adaptation, positive self-image, and emotional equilibrium related to person's capacity to adapt to change. The same situation may have different effects on different individuals.
