1 · What the graph read from it

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.

2 · The registry

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

This hospital-based study aimed to investigate the relationship between dietary omega-3 (DHA, EPA) and omega-6 (linoleic acid) fatty acid intake and sleep quality in older adults with type 2 diabetes mellitus (T2DM), addressing gaps in research on habitual (non-supplemental) intake patterns and their associations with sleep disturbances in this high-risk population. A case-control study included 193 hospitalized participants, divided into with sleep impairment (Pittsburgh Sleep Quality Index, PSQI ≥5) and without sleep impairment (PSQI <5) groups. Dietary intake was assessed via a validated 14-item food frequency questionnaire incorporating local food profiles. Sleep quality was measured using the PSQI. Logistic regression models evaluated associations between fatty acid intake thresholds and sleep impairment risk. Sleep-impaired individuals exhibited significantly lower marine ω-3 intake: DHA (284.5 vs 884.8 mg/d, P <.001) and EPA (134.7 vs 405.2 mg/d, P <.001). Adjusted models revealed consistent associations: DHA intake <583.1 mg/d increased sleep impairment risk by 2.81-fold (95% CI:1.61-4.92, P = .006), while EPA <269.3 mg/d conferred 1.99-fold higher risk (95% CI:1.05-3.75, P = .012). Total polyunsaturated fatty acid (PUFA) (OR = 1.62, P = .182) and linoleic acid intake (OR = 1.79, P = .842) showed no significant associations. Insufficient marine ω-3 intake, particularly DHA and EPA, is a modifiable risk factor for sleep impairment in older adults with diabetes.
