Tear Proteome Analysis with Patients with Primary Nasolacrimal Duct Obstruction.
Article in International journal of molecular sciences, 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
The pathogenesis of primary acquired nasolacrimal duct obstruction (PANDO) remains unclear, with several factors implicated, including anatomical structures, hormones, and tear components. This study explored tear proteins to better understand PANDO etiology by comparing protein expression in tears from patients with PANDO and healthy controls. Tear samples were collected from 22 patients with PANDO (mucous and membranous types) and 8 controls using Weck-Cel sponges. Protein analysis was conducted using LC-MS/MS to identify and quantify tear proteins. Female patients with PANDO had higher numbers of differentially expressed proteins (DEPs) compared with males. Certain DEPs associated with inflammatory pathways or the lacrimal duct epithelium, including SERPINB1, SERPINA3, CTSG, SLPI, and EZR, were identified in male patients. Although this is a preliminary study, our results offer insights into the pathogenesis of PANDO, with potential to distinguish between mucous and membranous subtypes. The potential biomarkers identified in this study could enhance early diagnosis and treatment, shedding light on inflammatory and immune processes in PANDO.
