Molecular epidemiological characteristics of pertussis in a pediatric hospital in Jinan City, China, 2022 to 2024.
Article in Frontiers in public health, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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: Pertussis is a highly contagious disease caused by Methods: We analyzed BP-positive cases identified by targeted sequencing for multiple respiratory pathogens in children aged 0-18 years with respiratory infections treated at our hospital from January 2022 to December 2024. Demographic characteristics, positivity rates, age distribution, and co-infecting pathogens were retrospectively assessed. Results: A total of 20,059 samples were included, with an overall BP positivity rate of 9.83%. The A2047G macrolide resistance mutation rate was significantly increased from 0.24% in 2022 to 6% in 2023 and 42.86% in 2024, respectively ( Discussion: This study reveals significant shifts in pediatric pertussis epidemiology during the post-pandemic era, characterized by rising incidence, non-seasonal surges, increased school-aged cases, and heightened co-detection rates. These findings call for enhanced drug-resistant BP surveillance, strengthened vaccination (especially among school-aged children in close contact with infants), improved clinical recognition, and targeted public health interventions to disrupt transmission.
