Topographical Quantification of Hyper-Reflective Foci May Predict the Development of Macular Atrophy in Patients With Neovascular Age-Related Macular Degeneration.
Article in Investigative ophthalmology & visual science, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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 purpose of this study was o examine the optical coherence tomographic (OCT) characteristics of hyper-reflective foci (HRF) in patients with neovascular age-related macular degeneration (nAMD) and to assess the potential of HRF as a predictive factor for the development of macular atrophy following anti-vascular endothelial growth factor (anti-VEGF) therapy. Methods: This was a retrospective analysis of 61 treatment-naïve eyes diagnosed with exudative AMD and type 1 macular neovascularization (MNV). The HRF was identified in the inner retina and outer retina layers, and the treatment response of HRF was documented. An analysis was conducted to explore the association between HRF and the development of macular atrophy. Results: The number of HRF in the inner retina and outer retina layers showed significant reduction after 12 months of anti-VEGF treatment (P = 0.002 and P < 0.0001, respectively). Similarly, compared with baseline, the number of HRFs in the inner retina and outer retina layers was significantly reduced after 24 months of anti-VEGF treatment (P = 0.002 and P < 0.0001, respectively). Moreover, the multivariate linear regression analysis revealed that the most substantial associations observed with the development of macular atrophy after 12 months were specifically tied to the number of HRFs in the outer retina (P = 0.039) at the baseline visit. This finding was confirmed after 24 months of anti-VEGF treatment (P = 0.007). Conclusions: After only 1 year of antiangiogenic therapy, there was a significant decrease in HRFs observed across all retinal layers. This reduction persisted even after 2 years of anti-VEGF treatment. Notably, the quantity of HRFs in the outer retina at baseline exhibited a correlation with the development of macular atrophy that endured at both the 1-year and 2-year follow-ups after anti-VEGF treatment.
