Oral rotavirus vaccine effectiveness among malnourished children in 19 countries: Findings from the MNSSTER-V project.
Article in Journal of pediatric gastroenterology and nutrition, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
objectivesRotavirus vaccine clinical trials and post-licensure evaluations found malnourished children may have lower protection against rotavirus diarrhea hospitalizations than well-nourished children. On a population level, rotavirus vaccines are less protective in high child mortality settings.
methodsWe analyzed rotavirus vaccine effectiveness (VE) among malnourished and well-nourished children categorized using four anthropometric malnutrition indicators, birthweight, and reported malnutrition from medium to high child mortality countries in the Multi-National Subpopulations Study to Evaluate Rotavirus Vaccines (MNSSTER-V) dataset. We calculated child-level z-scores for weight-for-age, length-for-age, weight-for-length, and mid-upper arm circumference (MUAC), and the site-level proportion implausible z-scores. Sites with published VE estimates by nutritional status or those with <3% implausible values were included in the final analysis. Z-scores <-2 were considered moderate-to-severe malnutrition and <-3 were considered severe malnutrition. We calculated complete series rotavirus VE in each malnourished and well-nourished group using an unconditional adjusted logistic regression model, where VE = (1 - odds ratio of vaccination among cases and controls) × 100, where cases and controls were children who tested rotavirus positive and negative, respectively.
resultsComplete series VE was more protective among children without stunting (normal length-for-age) (59%; 95% confidence interval [CI]: 49-67) compared to children with moderate-to-severe stunting (42%; 95% CI: 19-58) and severe stunting (31%; 95%CI: -14 to 58). Adjusted VE point estimates were similar among malnourished and well-nourished children using the other anthropometric and birthweight indicators.
conclusionsOur findings clearly show that chronic malnutrition negatively impacted rotavirus VE. Efforts to address and prevent malnutrition generally may further reduce the burden of rotavirus morbidity and mortality.
