Effect of the Coronavirus Disease 2019 Pandemic on Retinal Artery Occlusion.

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 determine the prevalence and clinical characteristics of retinal artery occlusion (RAO), including branch RAO (BRAO) and central RAO (CRAO), among new patients before and after the declaration of a state of emergency due to coronavirus disease 2019 (April 7, 2020) in Japan. Methods: New patients and patients with newly diagnosed RAO were categorized into "Before" and "After" groups based on the initial visit. The prevalence, sex ratio, and age of patients newly diagnosed with RAO were compared between the groups. The rates of patients newly diagnosed with rhegmatogenous retinal detachment (RRD) and pseudoexfoliation glaucoma (PEX) were also examined in the Before and After groups. Results: This study included 53 and 31 patients with BRAO and 55 and 40 patients with CRAO in the Before and After groups, respectively. There were no significant differences in prevalence of RAOs among newly diagnosed patients (BRAO: Conclusions: Although the coronavirus disease 2019 pandemic did not affect the prevalence of RAOs among new patients compared with that of RRD and PEX, it may have affected its pathophysiology.
