Association between tear lactoferrin, lysozyme, albumin levels, and obstructive sleep apnea syndrome: a cross-sectional study.
Article in Frontiers in medicine, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Background: Obstructive Sleep Apnea Syndrome (OSAS) is associated with various ocular diseases, but its relationship with tear biomarkers for dry eye remains unclear. This study aimed to investigate these tear biomarkers and their correlation with OSAS. Methods: This cross-sectional study was conducted at a tertiary hospital in Zhejiang Province from January 2021 to December 2022. Forty-one OSAS patients were enrolled. Tear lactoferrin, lysozyme, and albumin levels (exposure variables) were measured using ELISA, while OSAS (outcome variable) was diagnosed through polysomnography. Age, gender, and BMI were collected as covariates. Results: Baseline characteristics (including age, gender, and BMI) showed no statistical differences between groups. No significant correlations were found between tear albumin ( Conclusion: This study found no significant correlation between dry eye tear biomarkers levels and disease severity in OSAS patients. Larger-scale studies are needed to validate these findings.
