1 · What the graph read from it

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.

2 · The registry

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

objectivesIn Gujarat, indigenous oral pentavalent rotavirus vaccine, ROTASIIL was introduced in July 2019; however, post marketing research on this vaccine is currently lacking. This cross-sectional study was conducted among children aged < 5 y hospitalized with acute gastroenteritis in Rajkot, Gujarat with an aim to investigate the epidemiology of rotavirus gastroenteritis following rotavirus vaccine introduction in the Universal Immunization Program (UIP) of Gujarat.

methodsChildren aged < 5 y admitted with acute gastroenteritis between February 2021 and December 2023 were enrolled in the study. Data were collected on sociodemographic and clinical characteristics, and a copy of the child's vaccination card. Stool samples were collected and tested for rotavirus using an enzyme immunoassay. Rotavirus-positive samples were genotyped using reverse-transcription polymerase chain reaction.

resultsOf the 288 stool samples tested, 66 (22.9%) were rotavirus positive. The prevalence of rotavirus positivity was higher in children with five or more diarrheal episodes within 24 h than in those with fewer episodes and higher in vaccinated than in unvaccinated children. The prevalence of rotavirus positivity was lower in those with a length of hospital stay ≥ 5 d than in those with shorter stays, and in infants aged 0-5 mo than in older children. G3P[8] (48.5%) was the most prevalent rotavirus genotype, followed by G2P[4] (37.9%).

conclusionsRotavirus diarrhea remains prevalent among children hospitalized with acute gastroenteritis in Rajkot. G3P[8] and G2P[4] are the predominant circulating rotavirus strains.
