Relationship Between Sleep Quality and Glycemic Control Among Patients With Type 2 Diabetes.

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
backgroundThe quality of sleep has been identified as a significant contributor to the management of type 2 diabetes mellitus (T2DM), particularly in achieving optimal blood glucose levels. Although previous research globally has acknowledged this relationship, there is a lack of adequate studies in low- and middle-income countries, such as Pakistan. The purpose of this study is to investigate the relationship between self-management behavior (as indicated by glycemic control) and sleep quality among individuals with type 2 diabetes mellitus (T2DM).
methodsThis study is a cross-sectional study conducted from January to May 2025 in outpatient healthcare centers in Islamabad, Pakistan, using a convenience sampling methodology. The study included 385 adult respondents with a diagnosis of type 2 diabetes mellitus (T2DM). The structured questionnaire included sections on demographic characteristics, the Pittsburgh Sleep Quality Index (PSQI), and the Diabetes Self-Management Questionnaire (DSMQ). Data analysis was conducted using IBM Corp. Released 2020. IBM SPSS Statistics for Windows, Version 26. Armonk, NY: IBM Corp., employing descriptive statistics, Spearman correlation, Mann-Whitney U tests, Kruskal-Wallis H tests, chi-square tests, and linear regression to investigate the relationship between sleep quality and diabetic self-management practices.
resultsA total of 385 participants took part in the study, comprising 195 males (51%) and 190 females (49%). PSQI and DSMQ were also negatively correlated at a highly significant level (r = -0.119, p = 0.020), and this indicates that poor quality of sleep was interrelated with a low rate of self-management of diabetes. Female respondents also had significantly lower scores in sleep quality and reached higher scores in self-management than male respondents (p < 0.01). There were also significant differences in the PSQI and DSMQ scores, even when marital status was taken into account (p < 0.01). Based on the results of linear regression, it was possible to note that PSQI scores had a significant effect on predicting DSMQ scores (B = -0.452, p = 0.021); thus, the lower the score of the sleep quality measure, the less positive were the diabetes self-care behaviors.
conclusionIt was found that sleep quality and glycemic control behaviors predict a strong negative interrelationship in T2DM patients in Pakistan. The management of diabetes should consider including a sleep assessment. To achieve improved outcomes, recommended gender- and marital status-sensitive interventions are advised, including a targeted approach to self-management and sleep hygiene.
