1 · What the graph read from it

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.

2 · The registry

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

Two days after the second dose of the messenger RNA-based COVID-19 vaccine (BNT162b2), a healthy 38-year-old man developed branch retinal vein occlusion (BRVO) in his left eye (OS). His previous medical history was unremarkable and he was a nonsmoker. His blood pressure was 117/78 mm Hg. Blood examination did not suggest thrombophilia. His best-corrected visual acuity (BCVA) was 0.9 OS with myopic correction. A fundus examination showed a retinal hemorrhage and cotton wool spots in the superotemporal region of the posterior pole OS. Optical coherence tomography macular scans showed subfoveal fluid accumulation and retinal thickening in the superior macular region OS. Two intravitreal injections of aflibercept were administered 2 months apart. By 7 months after the initial visit, the BCVA was 1.2 OS and the retinal hemorrhage and macular edema have resolved. BRVO can be seen after BNT162b2 vaccinations. Because the third doses of the vaccine are beginning to be administered more widely, ocular complications including RVO can develop and require attention.
