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
backgroundMycoplasma pneumoniae (MP) is a leading cause of community-acquired pneumonia in children. The COVID-19 pandemic and associated public health interventions have significantly influenced the epidemiology of respiratory infections. This single-center retrospective cohort study aimed to evaluate changes in MP infection patterns among children before, during, and after the COVID-19 pandemic.
methodsWe analyzed data from 15,718 pediatric patients (aged 1–18 years) with CAP admitted to Shaanxi Provincial People’s Hospital between January 2017 and December 2023. The study periods were defined as pre-pandemic (January 1, 2017, to January 22, 2020), pandemic (January 23, 2020, to December 11, 2022), and post-pandemic (December 12, 2022, to December 31, 2023). Epidemiological characteristics of MP infections were assessed using descriptive statistics and regression analysis.
resultsAmong the 15,718 patients, 5,454 (34.7%) tested positive for MP. The highest positivity rate was observed in children aged > 6 years (52.4%), with a male predominance across all age groups. Most infections occurred in autumn (41.5%). The MP positivity rate was lowest during the pandemic period and highest in the post-pandemic period (P < 0.001). Regression analysis indicated a broadening of the susceptible age range following the pandemic onset.
conclusionCOVID-19 containment measures altered the transmission dynamics of MP, affecting demographic characteristics such as age distribution and seasonal trends. Continuous surveillance of MP epidemiology in the post-pandemic era is recommended to inform clinical management and public health strategies.
