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: To evaluate the presence, distribution, and potential implications of choroidal hyperreflective foci (HRFs) across different types of macular atrophy and their relationship with the size of atrophic regions. Methods: This retrospective case series analyzed 95 eyes from 87 patients with macular atrophy caused by various conditions, including geographic atrophy due to age-related macular degeneration, pachychoroid disease, punctate inner choroidopathy, angioid streaks, and Stargardt disease. Structural optical coherence tomography (OCT) images were evaluated to identify HRFs in different choroidal layers. HRF counts were correlated with the size of macular atrophy and underlying conditions using multiple regression analysis. Results: HRFs were observed in all cases, with their number significantly associated with the size of macular atrophy (P < 0.001). The highest HRF counts were found in Stargardt disease, while the lowest were in pachychoroid disease. However, no association was identified between HRF quantity and specific disease type (P = 0.2). HRFs were primarily located in the choriocapillaris, Sattler's layer, and near Bruch's membrane but were absent within choroidal vessels. Conclusions: HRFs represent a common OCT finding in various disorders associated with macular atrophy. Their quantity correlates with atrophy size rather than disease type, suggesting they are likely normal choroidal components rendered visible by RPE loss. Future studies are warranted to elucidate their origin and potential implications for disease progression.
