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

Objective: Diabetic retinopathy (DR) is a primary contributor to vision loss worldwide and growing with an increase in the elderly population. Preventing or slowing DR progression remains a critical unmet need. Recognizing the significance of systemic and ocular chronic inflammation in the progression of DR, this study aimed to explore inflammatory factor profiles in plasma and tear samples to identify potential biomarkers and therapeutic targets. Methods: Using Olink's proximity extension assay, 92 inflammation-related proteins were measured in paired plasma and tear samples of 42 participants in type 2 diabetes mellitus (T2DM), DR and Diabetic Macular Edema (DME), followed by bioinformatic analysis for differentially expressed proteins (DEPs). Results: Different expression patterns of inflammatory proteins were observed between plasma and tear level. Plasma DEPs was mainly decreased during DR development, while tears DEPs mainly upregulated. DME had more differential cytokines than DR in both samples. By multi-comparison analyses, 23 inflammatory factors exhibited differential expression in the three compared groups (DR vs T2DM, DME vs T2DM and DME vs DR) in plasma level, and 30 differential inflammatory cytokines in tear samples. GO and KEGG analysis enriched pathways were primarily associated with extracellular region, cytokine activity, IL17 signaling pathway and JAK-STAT signaling pathway. Conclusion: Tears exhibit more DEPs than plasma during the progression of DR and DME, and the two sample types show opposite inflammatory factor expression trends. The DEPs in tears, especially the newly discovered inflammatory factors TNFSF14, CXCL11, IL6, CCL19, DNER and CXCL9 may serve as potential biomarkers for the diagnosis and progression monitoring of DR and DME.
