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: Sleep quality is a common and often overlooked clinical issue among hemodialysis patients, which can affect physical and psychological quality of Life. This study intended to evaluate sleep quality and its determinants among patients receiving hemodialysis. Methods: A cross-sectional study was conducted at three hemodialysis centers in Anuradhapura and Polonnaruwa districts of Sri Lanka, including a random sample of 310 maintenance hemodialysis patients. The Pittsburgh Sleep Quality Index (PSQI) was used to assess the sleep quality of the patients. Socio-demographic information, dialysis and medical data, dietary and lifestyle information were also recorded. Several laboratory investigations were conducted before and after dialysis. Dialysis adequacy was calculated using single pool Kt/V. Multiple linear regression was performed to identify significant predictors of poor sleep quality. Results: A significant majority (83.3%) of the population exhibited poor sleep quality. According to the PSQI, poor sleep latency and low sleep duration were key contributing factors. A significant association was observed between the sleep quality of patients and the number of dialysis sessions per week ( Conclusion: The study revealed a striking prevalence of poor sleep quality in the population. According to the multiple linear regression model, dialysis center, dialysis access, number of dialysis side effects and complications, appetite and post dialysis serum urea level were identified as significant predictors of poor sleep quality in the population. Subsequent research should develop appropriate interventions to address inadequate sleep quality among hemodialysis patients.
