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

objectivesThis study assessed the global burden of glaucoma using data from the Global Burden of Disease (GBD) 2021 study. The analysis of epidemiological trends aimed to inform future public health prevention strategies.

designRetrospective cross-sectional study.

participantsNone.

methodsAnalysis of 1990-2021 GBD data on glaucoma prevalence, disability-adjusted life years (DALYs), age-standardised prevalence rates (ASPR), and age-standardised DALY rates (ASDR). Estimated annual percentage changes (EAPC) were calculated, Joinpoint regression identified trend changes, and Autoregressive Integrated Moving Average (ARIMA) modelling projected the burden for the year 2050.

resultsGlobally, the number of prevalent glaucoma cases increased from 4 072 106.59 (95% uncertainty interval (UI) 3 489 888.7 to 4 752 867.3) in 1990 to 7 587 672.9 (95% UI 6 522 906 to 8 917 725.4) in 2021. Concurrently, DALYs increased from 467 600.4 (95% UI 323 490.5 to 648 641.6) in 1990 to 759 900.2 (95% UI 530 942.9 to 1 049 127.2) in 2021. In contrast, the ASPR and ASDR declined to 90.1 per 100 000 population (95% UI 77.8 to 105.5) and 9.1 per 100 000 population (95% UI 6.3 to 12.5) in 2021, respectively. During the COVID-19 pandemic period (2019-2021), the slowest growth rates in crude case numbers and overall disease burden were observed, accompanied by the most pronounced decline in annual percentage change of ASPR. The highest estimates for both case counts and DALYs were identified in the 70-74 age group, with males demonstrating higher prevalence rates than females. Furthermore, regions with lower Sociodemographic Index (SDI) values bore a disproportionately higher burden of glaucoma.

conclusionThese findings underscore the need to strengthen early screening and treatment of glaucoma, particularly in ageing populations, male groups and low SDI regions. We urge cautious interpretation of COVID-19 related data and vigilance against potential post-pandemic surges in burden. Critical strategies include enhanced screening and intervention for high-risk groups, targeted prevention measures and integration of ophthalmic care into public health emergency frameworks to alleviate the disease burden.
