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
BACKGROUND Purtscher retinopathy (PR) is a rare, vision-threatening retinal disorder that usually develops after trauma. It is characterized by retinal hemorrhages and areas of retinal whitening, which are thought to result from microvascular occlusion of precapillary retinal arterioles. Advances in imaging, particularly optical coherence tomography angiography (OCT-A), have provided valuable insights into the microvascular alterations associated with PR and offer strong evidence supporting its ischemic pathogenesis. We report a case demonstrating ischemic changes in retinal and choroidal circulation and discuss their prognostic significance. CASE REPORT A 63-year-old man with head neck trauma presented with acute, painless vision loss in the right eye. Initial ophthalmic examination revealed cotton-wool spots, retinal whitening, Purtscher flecken, and retinal hemorrhages. OCT showed hyperreflectivity of the inner retinal layers, subretinal fluid, and internal limiting membrane detachment. OCT-A demonstrated extensive capillary non-perfusion in both the superficial and deep retinal plexuses, as well as suspected ischemia at the level of the choriocapillaris. PR was diagnosed, and high-dose systemic corticosteroid therapy was initiated. At 3-month follow-up, retinal edema, cotton-wool spots, and Purtscher flecken had resolved; however, persistent non-perfusion of the retinal plexuses and subtle impairment of choriocapillaris perfusion were still evident. Final best-corrected visual acuity remained poor due to ischemic atrophy involving the retina, choroid, and optic nerve. CONCLUSIONS PR can involve both the retinal and choroidal circulation. OCT-A is a fast, safe, and non-invasive modality for identifying and monitoring these microvascular alterations. Combined retinal and choroidal ischemia in PR can be associated with poor visual outcomes.
