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 report a case of peripapillary pachychoroid syndrome (PPS) complicated with peripapillary retinal neovascularization causing vitreous hemorrhage. Observation: A 42-year-old man, with a history of a visual loss of the right eye (RE) for 4 years, presented for ophthalmological examination. Best-corrected visual acuity was «counting fingers» in the RE and 20/25 in the left eye. Fundus examination showed irregular pattern of hypopigmentation of the retinal pigmented epithelium in both eyes with retinal neovessels in the peripapillary region of the RE. Swept-source optical coherence tomography demonstrated a central serous pigment epithelial detachment with intraretinal cysts and serous retinal detachment in the nasal macula extending from the temporal disc margin in the RE. Fluorescein angiography showed multiple areas of hyperfluorescence without clear distinction of retinal neovessels. Indocyanine green angiography showed patches of choroidal hyperpermeability predominant in the peripapillary region in both eyes. Optical coherence tomography angiography provided a good visualization of the papillary and retinal neovessels without signs of choroidal neovascularization. Two months after initial examination, the patient presented with vitreous hemorrhage associated to juxtapapillary preretinal hemorrhage in the RE. After vitreous injections of bevacizumab, we observed a total resolution of the vitreous hemorrhage a partial decrease of the intraretinal and subretinal fluid. Conclusions and importance: We report an unusual case of peripapillary retinal neovascularization and vitreous hemorrhage complicating a PPS. OCTA was useful to detect retinal neovessels and peripapillary retinal and choriocapillaris hypoperfusion, supporting the understanding of the pathogenic mechanism of neovascularization in PPS.
