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
Purpose This study aimed to assess the prevalence of insomnia in adults with type 2 diabetes mellitus and its association with glycated hemoglobin. Methods In this cross-sectional study, patients attending a diabetes clinic completed the Insomnia Severity Index and the Hospital Anxiety and Depression Scale (HADS). Glycated hemoglobin values were self-reported by participants based on their most recent laboratory result. Logistic and linear regression analyses evaluated demographic and psychological predictors of insomnia and the relationship between insomnia and glycated hemoglobin. Results The prevalence of clinically significant insomnia symptoms was 37.7%. Higher HADS total scores were independently associated with insomnia, while age, sex, and glycated hemoglobin were not significant predictors. Insomnia status was not significantly associated with glycated hemoglobin levels (coef.=0.04; p=0.28). However, age, sex, and glycated hemoglobin each independently predicted total HADS score (all p<0.01), suggesting a multifaceted interplay among demographic, metabolic, and psychological factors. Conclusions Insomnia affects over a third of adults with type 2 diabetes mellitus, but was not independently associated with glycated hemoglobin. Routine sleep and mental health screening, especially in younger patients, could improve well‑being and type 2 diabetes mellitus management.
