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
Importance: The coronavirus disease 2019 (COVID-19) pandemic and associated non-pharmaceutical interventions (NPIs) have significantly altered the epidemiology of respiratory pathogens. Understanding the interactions between non-bacterial respiratory pathogens is crucial for clinical management and surveillance. Objective: To investigate how interactions among non-bacterial respiratory pathogens in children changed during and after the COVID-19 pandemic in two cities in eastern China. Methods: This retrospective study reviewed the data of children hospitalized with acute respiratory tract infections in Wenzhou and Ningbo between March 1, 2021, and February 28, 2024. The SureX 13 respiratory pathogen multiplex kit was used to detect 13 pathogen types/subtypes in the respiratory tract secretion specimens. The chi-square test or Fisher's exact test, virus correlation, and vector autoregressive modelling were employed to evaluate correlations and dynamic changes in the weekly positive detection rates before and after the NPIs. Results: Among the 73 096 children tested, 65.18% had at least one non-bacterial respiratory pathogen, and 11.97% had multiple pathogens. Detection rates declined significantly by 56.65% during NPIs but rebounded by 75.46% afterward, particularly for Interpretation: The interactions between non-bacterial respiratory pathogens markedly changed after COVID-19, showing strengthened correlations, which were primarily negative in nature. These observations underscore the importance of the ongoing surveillance of respiratory pathogens in evolving NPIs and epidemiological patterns.
