Worldwide ophthalmological research production 2000-2020, with special focus on the Nordic contribution.
Article in Acta ophthalmologica, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers, 1 of them a synthesis that pooled 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.
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
purposeTo explore the trends in worldwide ophthalmic research production over a 21-year period in relation to journals, contributing countries and dominating topics with special focus on the Nordic region.
methodsArticles published between 2000 and 2020 in 20 top-ranked ophthalmology journals were included. Number of articles and impact points were measured per country for each year. The most frequently occurring keywords were calculated worldwide and for the top five contributing countries and the Nordic countries. Trends were explored using linear regression.
resultsThe analysis included 65 220 articles. Linear regression showed an increase with 56 articles per year (β = 56.3, R
conclusionsThe worldwide ophthalmic research productivity has maintained a growing trend from 2000 to 2020. While North America and Europe are the major contributors, the scientific activity in Asia and especially China is growing impressively. With the current progress, Asia is forecast to outweigh Europe in 2025 and North America in 2033. Diabetic retinopathy was the most common eye disease in ophthalmologic papers in 2020, and also the topic with the strongest positive trend during 2000-2020.
