Impact of COVID-19 on the epidemiological features of mycoplasma pneumoniae infection in children with community-acquired pneumonia in Ganzhou, China.

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
Background: The COVID-19 pandemic and non-pharmaceutical interventions (NPIs) have altered the global epidemiology of respiratory pathogens, including Methods: We retrospectively analyzed 27,369 hospitalized pediatric CAP patients (2017-2024), comparing MP positivity, seasonality, age distribution, and severity across pre-pandemic, NPIs, and post-NPIs phases. Results: Among 27,369 CAP patients, 3,334 were MP-positive (12.18%). The positivity rate dropped during Phase II (3.78%, 158/4,183) then rebounded sharply in Phase III to 21.17% (2,385/11,268), exceeding the pre-pandemic baseline (χ²=45.65, Conclusion: After the relaxation of NPIs, pediatric MP infections among hospitalized pediatric CAP patients in Ganzhou not only rebounded strongly but also exhibited a shift in epidemic peaks toward spring, alongside a notable change in susceptibility among younger children.
