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

backgroundAsthma represents a significant global health challenge, exhibiting considerable variation in prevalence, incidence, mortality and disability-adjusted life years (DALYs) across regions and countries. This study evaluates global, regional and national trends in asthma burden from 1990 to 2021, analysing associations with temporal, geographical and demographical factors.

methodsUsing open data from the Global Burden of Disease (GBD) database (1990-2021), we analysed changes in asthma prevalence, incidence, mortality and DALYs by gender, age and Socio-Demographic Index (SDI) groups. Joinpoint regression analysis calculated the average annual percentage change (AAPC) and annual percentage change (APC).

resultsFrom 1990 to 2021, the age-standardised prevalence and incidence rates of asthma declined by 40.01% and 29.89%, respectively. While asthma deaths increased slightly, the age-standardised mortality rate (ASMR) declined by 46.01%. The highest prevalence was observed in South Asia, East Asia and high-income North America, while low-SDI regions exhibited elevated mortality and DALYs. The age and sex-specific patterns indicated a higher asthma burden among females. The results of the joinpoint analysis indicated a global age-standardised incidence rate increase between 2005 and 2010 for both males and females. The ASMR exhibited a statistically significant decline from 1990 to 2021.

conclusionsThe global age-standardised rate of asthma burden declined from 1990 to 2021. However, asthma remains a significant public health issue, particularly in regions with lower socioeconomic development. Understanding global and regional trends in asthma can inform future policies and interventions, aiming to promote more equitable prevention, diagnosis and treatment worldwide.
