Rotaviruses A and C in dairy cattle in the state of Rio de Janeiro, Brazil.
Article in Brazilian journal of microbiology : [publication of the Brazilian Society for Microbiology], 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Stool samples were collected from calves from nine family-based small dairy farms in the state of Rio de Janeiro, for detection and characterization of rotavirus (RV) species A, B, and C (RVA, RVB, and RVC, respectively) by reverse transcription polymerase chain reaction. Twenty-six samples (27.7%) were positive for at least one of the species: 22 (23.4%) samples were positive only for RVA, 3 (3.2%) were positive for RVC, and one sample (1.1%) had co-infection of RVA and RVC. RVB was not detected. Seven (21.9%; n = 32) animals with diarrhea and 19 (30.1% n = 62) asymptomatic animals were positive, with no significant difference in positivity (p = 0.3677). RV was detected in all properties studied, at rates between 14.3 and 80%, demonstrating the widespread circulation of RV in four of the seven geographic regions of the state of Rio de Janeiro. Infection was more prevalent among animals ≤ 6 months of age. Sequence analysis of a portion of the RVA VP6-encoding gene identified the I2 genotype. RVC was also detected; to our knowledge, this is the first description of this agent in cattle in Brazil. The data presented here should add knowledge regarding the importance and prevalence of RV in our national territory, and may facilitate the planning and implementation of control and prevention measures for bovine rotavirus infections in Brazil.
