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
aimsAlthough diabetes is linked to sleep disorders that can reduce quality of life (QOL) and increase depression risk, these conditions are still rarely assessed in clinical practice. This study aimed to evaluate sleep quality in older adults with type 2 diabetes (T2D) and its association with QOL and depressive symptoms.
methods151 individuals with T2D aged > 60 years without known sleep disorders underwent a review of clinical history and therapy, biochemical exams, and assessment of Pittsburgh Sleep Quality index (PSQI), World Health Organization QOL Bref (WHOQOL-BREF) scale, and Geriatric Depression Scale (GDS). The population was then split into: Good Sleepers (PSQI ≤ 5) and Poor Sleepers (PSQI > 5).
resultsThe prevalence of low sleep quality was 63.6%. Poor Sleepers showed numerically comparable age, sex, body mass index, diabetes duration, and glycaemic control with Good Sleepers. However, Poor Sleepers showed lower scores in the physical health and psychological health domains of WHOQOL-BREF. After adjusting for confounders, PSQI score was associated with CVD (β = 0.26, P = 0.008) and diabetes duration (β = 0.24, P = 0.022). Furthermore, the scores in the physical health (β=-0.35) as well as the psychological health (β =-0.31) domains of the WHOQOL-BREF and the GDS (β = 0.24) were all independently associated with PSQI score (all P < 0.05).
conclusionsIn our population of older adults with T2D, poor sleep quality was highly prevalent and associated with poor quality of life and depressive symptoms. Thus, sleep quality assessment should be carefully considered in clinical practice, especially in people with long diabetes duration and complications.
