Rotavirus Infection in Children Suffering from Diarrhea in Patna, Bihar Region, India: A Hospital-Based Study.
Article in The American journal of tropical medicine and hygiene, 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
Rotavirus (RV) is a leading cause of severe gastroenteritis in infants and young children, often resulting in dehydration and hospitalization. Although global data on RV is well-documented, there is limited information on its prevalence and genetic diversity in Bihar, India. This study aimed to investigate the prevalence of RV infections in the patient, from January 2021 to June 2024, and assess the associated molecular and epidemiological patterns. In this retrospective study conducted at the Rajendra Memorial Research Institute of Medical Sciences, Patna, 1,820 stool samples from patients suspected of RV infection were collected. Enzyme immunoassays were used to detect RV antigens, and positive samples were confirmed by real-time polymerase chain reaction targeting the VP4, VP6, and VP7 genes. Phylogenetic analysis was performed to examine genetic diversity. Results showed a 10% positivity rate for RV, with 5% showing equivocal results. The highest prevalence was in the 6-11 years age group (72 positive cases), followed by the 0-5 years group (62 positive cases). Prevalence decreased in older age groups, suggesting immunity through natural infection or vaccination. Phylogenetic analysis revealed distinct regional clusters and genetic variability between strains from Bihar and other parts of India, such as New Delhi and Kolkata. This study provides valuable baseline data on RV prevalence and genetic diversity in Bihar, emphasizing the need for vaccination and surveillance, particularly for younger children at higher risk. The observed genetic diversity suggests regional variations, highlighting the importance of continuous surveillance across India.
