Lifestyle habits, gender differences, and their association with sleep and mental health among Syrian medical residents.

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
backgroundMedical residency is a demanding phase that often compromises sleep quality and mental health. This study aimed to assess the association between lifestyle factors-specifically smoking, caffeinated beverage intake, alcohol consumption, and body mass index-with sleep quality, anxiety symptoms, and depressive symptoms among medical residents in Syria.
methodsThis manuscript reports a secondary analysis of the dataset collected and described by Soqia et al. This multicenter cross-sectional study was conducted across 22 hospitals in Syria, enrolling 2,047 medical residents. Validated instruments were used to assess outcomes: the Pittsburgh Sleep Quality Index for sleep quality, the Patient Health Questionnaire-9 for depressive symptoms, and the Generalized Anxiety Disorder-7 scale for anxiety symptoms. Logistic regression analyses were conducted to investigate the relationships between lifestyle habits and mental health outcomes.
resultsSmoking was significantly associated with poor sleep quality (odds ratio 1.33), depressive symptoms (odds ratio 1.36), and anxiety symptoms (odds ratio 1.26). Among female residents, coffee and alcohol consumption were linked to increased anxiety symptoms, with odds ratios of 1.39 and 2.56, respectively. An underweight body mass index was associated with a lower likelihood of poor sleep quality (odds ratio 0.17), depressive symptoms (odds ratio 0.33), and anxiety symptoms (odds ratio 0.51) in female participants.
conclusionsLifestyle habits such as smoking, caffeine and alcohol intake, and body weight status were significantly associated with sleep quality and mental health among Syrian medical residents. Interventions promoting smoking cessation, sleep hygiene, and moderated consumption of stimulants and alcohol may improve well-being and professional performance in this population.
