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 and atopic dermatitis (AD) represent significant global health challenges in children. This study aimed to investigate trends in incidence, prevalence, and disability-adjusted life years (DALYs) for childhood asthma and AD from 1990 to 2021.

methodsThe study utilized information from the Global Burden of Disease (GBD), Injuries, and Risk Factors Study 2021. The sample size for this study consisted of children with asthma or AD between the ages of 0 and 14. From 1990-2021, we calculated asthma and AD's age-standardized incidence, prevalence, and DALYs by area, age, sex, and socio-demographic index.

resultsIn 2021, global childhood asthma prevalence reached 95.7 million cases (age-standardized rate: 4,758 per 100,000), with the Low SDI region recording 25.4 million cases. For AD, global prevalence was 72.4 million cases (age-standardized rate: 3,600 per 100,000), predominantly in Middle SDI regions (19.7 million cases). Between 1990 and 2021, age-standardized incidence rates decreased for both conditions. Geographic variations were notable: High-income North America showed the highest asthma incidence, while Western Europe led in AD prevalence. The global burden of asthma-related DALYs declined from 6.9 million in 1990 to 4.6 million in 2021, with significant regional disparities.

conclusionsDespite decreasing age-standardized rates, childhood asthma and AD continue to pose substantial health burdens globally, with marked variations across regions and socioeconomic strata. These findings emphasize the need for targeted, region-specific interventions.
