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
backgroundAsthma, a prevalent chronic respiratory disease, significantly contributes to global morbidity and mortality. This study aimed to assess the disease burden, trends, and associated risk factors of asthma, stratified by sex and age groups, across 204 countries and territories.
methodsAsthma mortality, incidence, prevalence, and DALYs data were sourced from GBD Study 2021. Joinpoint and ARIMA models analyzed trends and projected future burdens over 15 years.
resultsThe 2021 global asthma data reveal age-sex specific disparities. Globally, the number of asthma incident episodes was 19,331,938 in males and 18,532,237 in females. However, females exhibited higher prevalence, mortality, and DALYs compared to males. Furthermore, age-standardized rates of asthma burden also varied by sex and age. Males generally presented higher incidence and mortality rates, whereas females showed higher DALYs and prevalence rates. Comparing different age and sex groups, males under 15 years of age experienced a greater asthma burden, a trend that reversed post-puberty. The highest incidence rates of asthma was observed in children under 5 years old, however, the highest mortality and DALYs rates were observed in individuals over 70 years old. From 1990 to 2021, the age-standardized asthma burden demonstrated a decreasing trend, with a more pronounced decline in males. In 2021, the primary risk factors for asthma were high body mass index, smoking, occupational asthma, and nitrogen dioxide exposure.
conclusionsDuring the period, age-standardized asthma burden rates declined, with a more pronounced decrease observed in males. However, in 2021, the overall burden of asthma remained substantial. Asthma exhibits distinct age-sex differences. Globally, high body mass index has emerged as an increasingly significant risk factor for asthma.
