The Impact of Non-pharmacological Interventions Measures Against COVID-19 on Respiratory Virus in Preschool Children in Henan, China.
Observational study in Journal of epidemiology and global health, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers.
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 investigate the long-term effects of non-pharmacological interventions (NPIs) measures on the epidemiological characteristics of common respiratory viruses in preschool children in Henan, China.
methodsThis was a retrospective observational study containing data from 17 prefecture-level cities in Henan, China. We analyzed and compared laboratory results and clinical data of preschool children presenting to outpatient clinics for acute respiratory infections (ARTI) after COVID-19 (January 2020-October 2022) and before COVID-19 (December 2017-December 2019). Each year was divided into quarters. The ratio of the odds ratios (ORs) of testing positive for eight respiratory viruses in each year after the pandemic to the prepandemic period was estimated applying a generalized linear model (GLM), using the mean of the positive detection rates in 2018-2019 as a reference.
resultsA total of 11,400 children were enrolled from December 2017 to October 2022. The number of positive detections for all respiratory viruses decreased in 2020-2022 compared to the average of 2018-2019. Human respiratory syncytial virus (hRSV), human rhinovirus (hRV), and influenza virus (IFV) accounted for a larger proportion of all detected viruses before COVID-19 pandemic, whereas hRV, human bocavirus (hBoV), and human adenovirus (hAdV) accounted for a significantly larger proportion after COVID-19 pandemic. The positive detection rates of enveloped viruses [IFV, human parainfluenza virus (hPIV), hRSV, human metapneumovirus (hMPV), and human coronavirus (hCoV)] decreased sharply and the seasonal activity of these viruses was weakened, while the positive detection rates of non-enveloped viruses (hRV, hBoV, and hAdV) increased, especially hRV. The conditions described above tended to occur more frequently in boys and children older than 1 year, and they were also more sensitive to the NPIs.
conclusionsNPIs transformed the epidemiological profile of common respiratory viruses among preschool children during the COVID-19 pandemic. To improve the overall public health response to all respiratory viruses, interventions targeting non-enveloped viruses need to be strengthened to mitigate their continued transmission.
