Tear fluid participates in systemic immunity.
Review in Zhong nan da xue xue bao. Yi xue ban = Journal of Central South University. Medical sciences, 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
Tear fluid, also referred to as tears or tear film, is an important biological fluid that plays a key role in maintaining ocular surface health and immune homeostasis. Recent studies have found that tear fluid not only participates in the occurrence and development of ocular diseases, but also exerts profound effects in the immune pathological mechanisms of systemic diseases, breaking through the inherent understanding previously held by the scientific community. Immune cells in tear fluid (such as T cells, neutrophils, natural killer cells, macrophages), cytokines, and immunoglobulins can specifically participate in autoimmune diseases (such as Sjögren's syndrome, rheumatoid arthritis, systemic lupus erythematosus, multiple sclerosis, Graves' ophthalmopathy) and systemic diseases (such as Alzheimer's disease, diabetes mellitus, graft-versus-host disease). The dynamic changes in tear fluid components can reflect systemic immune homeostasis imbalance. Tear fluid biomarkers, such as exosomal microRNA (miR)-204, miR-200b-5p, and the protein marker β2-microglobulin, have shown great potential in early disease screening, diagnostic stratification, and therapeutic target discovery. Tear fluid immune component analysis may provide innovative diagnostic tools and therapeutic targets for systemic diseases. Future research should focus on promoting the standardization and clinical transformation of tear fluid testing technologies and their clinical application.
