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
backgroundOn 1 January 2019, a 2-dose mumps-containing vaccine (MuCV) immunization strategy was adopted in Henan Province before the national Expanded Program on Immunization (EPI). This study examines the epidemiological characteristics of mumps cases during the implementation of various immunization strategies in Henan Province.
methodsWe employed descriptive statistics and initially retrieved data on reported cases from 2004 to 2024. Mumps case data were sourced from the China Information System for Disease Control and Prevention (CISDCP).
resultsBetween 2004 and 2024, a total of 301,342 cases of mumps disease were reported in Henan Province, and the average annual reported incidence was 15.11 cases per 100,000 people. The average yearly incidence decreased by 60.29% following the implementation of the 2-dose vaccination strategy compared with the one-dose strategy. The study identifies two annual incidence peaks from 2004 to 2024: a prominent peak from April to July and a smaller peak from December to January. From 2019 to 2024, in addition to a slight dip in February, the seasonality was less pronounced, with cases distributed sporadically throughout the year. The proportion of the population over 20 years old increased annually, from 8.17% in 2004-2008 to 15.55% in 2019-2024. There was an overall negative correlation between the estimated MuCV vaccination rate and the reported incidence of mumps (r = -0.685,
conclusionsThe introduction of 2-dose MuCV in the EPI significantly reduced the incidence rate and total number of cases. While continuing the 2-dose MuCV immunization strategy in the future, it is crucial to remain vigilant in preventing and controlling mumps among individuals over 20 years old.
