Prevalence of dry eye disease and its association with sleep quality and depression: a hospital-based survey in Thai population.
Article in BMJ open, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
objectivesTo estimate the prevalence of dry eye disease (DED) and explore its association with depression and poor sleep quality.
designA cross-sectional study.
settingThe study was conducted at the ophthalmology outpatient clinic of a tertiary university hospital in Thailand, from September 2022 to April 2023.
participantsA total of 1321 patients aged 18 years or older, without any history of orbital disease, active superficial or intraocular infection/inflammation, eyelid pathology, or prior intraocular or eyelid surgery within the past 6 months, were enrolled in the study.
interventionsAll patients underwent dry eye examination, including the Ocular Surface Disease Index questionnaire, tear break-up time and ocular surface staining. Physical activity was measured using the Global Physical Activity Questionnaire, which was expressed as total Metabolic Equivalent of Task-minutes per week. Sleep quality was assessed using the Pittsburgh Sleep Quality Index (PSQI), Composite Scale of Morningness (CSM) and STOP-Bang. Depressive symptoms were measured using the Patient Health Questionnaire (PHQ-9). PRIMARY AND SECONDARY OUTCOME MEASURES: Prevalence of DED and association pathways involving depression, sleep quality and DED.
resultsThe mean age of the participants was 58.3±14.0 years, with a female predominance of 73.7%. Of the 1321 patients, 668 were diagnosed with DED, resulting in a hospital-based prevalence of 50.6% (95% CI: 47.8%, 53.3%). After adjusting for age, sex and underlying disease, PSQI, PHQ-9, STOP-Bang and CSM scores remained significantly associated with DED with adjusted ORs of 2.48 (95% CI: 1.96, 3.14; p<0.001), 1.65 (95% CI: 1.05, 2.61; p=0.031), 1.81 (95% CI: 1.05, 3.14; p=0.033) and 1.32 (95% CI: 1.04, 1.68; p=0.023), respectively. The effects of depression on DED were mediated indirectly via poor sleep quality (OR=1.32; 95% CI: 1.18, 1.49; p<0.001) and directly via other mechanisms (OR=1.66; 95% CI: 1.06, 2.58; p=0.021).
conclusionsDED is notably common among Thai patients. Depression and poor sleep quality are significantly associated with DED. Poor sleep quality may mediate the relationship between depression and DED.
