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
objectivesTo analyze trends and future projections of lower respiratory infection (LRI) incidence and mortality among children in China from 1990 to 2021, and to compare etiological characteristics across age groups.
methodsEpidemiological data for pediatric LRI in China from 1990 to 2021 were obtained from the Global Burden of Disease database. Comparative analyses examined trends and projections for China, the global population, and high socio-demographic index (SDI) regions. The influence of different pathogens on pediatric LRI in China was also assessed.
resultsFrom 1990 to 2021, the burden of LRI among children in China was lower than the global average but higher than that in high-SDI regions. Incidence and mortality rates showed a significant downward trend, with the most pronounced decline in children under 5 years of age, while the decline in LRI incidence among those aged 10-14 years was slower than the global level for the same age group. Projections for 2022-2040 indicated continued decreases in incidence and mortality of pediatric LRI in China. Bacterial infections remained the predominant cause of pediatric LRI in China. Marked age-specific differences in pathogen spectra were observed: viral LRI burden was higher in children under 5 years than in those aged 5-14 years, whereas the burden due to atypical pathogens was lower in children under 5 years than in those aged 5-14 years.
conclusionsFrom 1990 to 2021, the overall burden of pediatric LRI in China shows a declining trend and is predicted to continue to decrease. The slower decline in LRI incidence among children aged 10-14 years compared with the global level indicates a weakness in prevention for this age group. Distinct age-specific pathogen profiles suggest the need for age-targeted interventions and continuous surveillance of pathogen spectra.
