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
Background Medical residency training is associated with high workload, psychological stress, and irregular sleep schedules, all of which may negatively affect sleep quality and mental well-being. Although physical activity is known to improve sleep and psychological health, limited evidence exists regarding its independent association with sleep quality among Saudi board trainees. Aim This study aimed to estimate the prevalence of poor sleep quality and identify its predictors among Saudi board trainees. Methods This cross-sectional survey study used an online, self-administered questionnaire that covered participants' demographics and personal characteristics. Sleep quality was assessed using the Pittsburgh Sleep Quality Index (PSQI), physical activity was evaluated using the short form of the International Physical Activity Questionnaire (IPAQ-SF), and anxiety and depression were screened using the four-item Patient Health Questionnaire (PHQ-4). Logistic regression models were applied to identify factors associated with poor sleep quality. Results The prevalence of poor sleep quality was 51.5% (101/196). Univariable logistic regression analysis revealed that several factors were significantly associated with increased odds of poor sleep quality, including being a junior resident (OR: 1.188, 95% CI: 1.032-1.366, p=0.017), use of sedative medications (OR: 1.640, 95% CI: 1.327-2.027, p<0.001), anxiety (OR: 1.482, 95% CI: 1.148-1.913, p=0.003), depression (OR: 1.495, 95% CI: 1.104-2.024, p=0.010), and mixed anxiety and depression (OR: 1.757, 95% CI: 1.482-2.083, p<0.001). However, in the multivariable logistic regression model, only the use of sedative medications and the presence of anxiety and/or depression remained independently associated with poor sleep quality. Residency level and physical activity did not retain statistical significance. Conclusions Anxiety and depression emerged as the most significant factors associated with poor sleep quality among Saudi residency trainees. Although physical activity initially appeared protective, it was not independently associated with sleep quality after adjusting for other relevant variables. Further research is needed to better understand the underlying mechanisms and consequences of anxiety and depression to guide strategies for improving sleep and well-being among Saudi residents.
