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

purposeThe elderly are at higher risk for sleep disorders and dry eye. This study explored correlations between dry eye and sleep quality in elderly individuals.

methods58 elderly dry eye patients and 31 controls were enrolled. Sleep quality was evaluated using Pittsburgh Sleep Quality Index (PSQI) and wearable intelligent devices. Dry eye symptoms and signs were assessed via Ocular Surface Disease Index (OSDI), Fluorescein tear breakup time (FBUT), Corneal fluorescein staining score (CFS) and Schirmer I test.

resultsThe dry eye group showed significantly worse OSDI, FBUT, CFS, Schirmer I, and PSQI scores versus controls (all P < 0.01), with reduced deep sleep duration (P = 0.02) and deep sleep percentage (P < 0.01). Among dry eye patients, 69.0% had poor sleep, and 94.8% slept less than 8 h (mean: 6.51 ± 0.83 h). Subjective sleep quality correlated with FBUT and CFS (P < 0.05). A correlation was found between deep sleep percentage (%) and FBUT (r = 0.296, P < 0.05) and CFS (r=-0.418, p < 0.01). Prolonged video terminal use reduced deep sleep percentage (%) (F = 5.18, P < 0.01) and worsened FBUT (P < 0.01).

conclusionsElderly dry eye patients exhibit poorer sleep quality. Reduced deep sleep percentage (%) in elderly correlates with dry eye, and excessive video terminal use may contribute.
