Chemokine System Changes Drive Age-Related Macular Degeneration and Influence Treatment Outcomes.
Article in Investigative ophthalmology & visual science, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
Purpose: The chemokine system is associated with age-related macular degeneration (AMD), shown in previous studies. In this study, we investigate these chemokines and chemokine receptors and their association with treatment response in neovascular AMD (nAMD), and association to intermediate AMD (iAMD). Methods: In this prospective cohort study, patients with nAMD, iAMD, and healthy controls were included. The initial and 1-year treatment response was evaluated in patients with nAMD. Plasma chemokine concentrations of CCL2, CCL3, CCL4, CCL20, CXCL8, and CXCL10 were measured with immunoassays. Chemokine receptor expression levels of CCR1, CCR2, CCR5, CCR6, CXCR2, CXCR3, and CX3CR1 on circulating T cells and monocytes were measured with flow cytometry. Correlation network analyses were performed of the chemokine system. Genotyping for CFH and ARMS2 risk polymorphisms was performed in patients with nAMD. Results: Patients with nAMD with poor initial treatment response had significantly lower proportions of CD4+CXCR3+, CCR5+ classical monocytes, and CCR2+ non-classical monocytes compared with good initial responders (all P < 0.05). Patients with nAMD with poor 1-year treatment response had significantly lower CD4+CXCR3+ and CCR2+ non-classical monocytes compared to good 1-year responders (both P < 0.05). Correlation networks revealed a more complex regulation in partial and poor initial treatment responders. Multiple chemokines and chemokine receptors significantly correlated with the risk genotypes of CFH and ARMS2. Conclusions: Patients with nAMD with poor treatment response had dysregulation of the chemokine system. The chemokine system might be a potential target of novel treatment in nAMD. Further studies are needed to clarify the chemokine system's role in nAMD treatment response.
