Epidemiology and Clinical Profile of Rotavirus Diarrhea in Children Aged Under 5 Years in Kerala, India After the Introduction of Rotavirus Vaccination: A Surveillance Study.
Observational study in Indian journal of pediatrics, 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
objectivesROTASIIL
methodsThis prospective observational study was conducted at three tertiary-care hospitals in Kerala from November 2020 to December 2023. Children aged under 5 y who were hospitalized with acute diarrhea were enrolled. Stool samples were collected from participants and tested for rotavirus using an enzyme-linked immunosorbent assay. Rotavirus-positive samples were genotyped.
resultsOf the 666 children enrolled, 643 had a stool sample tested for rotavirus, of which 17.9% tested positive. Rotavirus diarrhea occurred throughout the year, with a small peak between December and February. Most children with acute rotavirus diarrhea (56.5%) were aged 24-59 mo. The incidence of rotavirus-positive and rotavirus-negative acute diarrhea was higher among boys than among girls (male-to-female ratio of 1.3:1 and 1.5:1, respectively). The prevalence of rotavirus positivity was lower in children who had received three doses of oral rotavirus vaccine, ROTASIIL
conclusionsIn children hospitalized with acute diarrhea, the prevalence of rotavirus was lesser among vaccinated than unvaccinated children. Monitoring of age shift, breakthrough infections in vaccinated children, and genotypic surveillance of emerging rotavirus genotypes are required to inform the development of next-generation vaccines.
