Molecular detection and genotyping of HMPV in patients with severe acute respiratory infection in India.
Article in Annals of medicine, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 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
backgroundHuman metapneumovirus (HMPV) is a common respiratory pathogen that causes respiratory tract infections. In India, HMPV has been identified as one of the leading causes of morbidity and mortality in infants and young children with respiratory tract infections. The most reported sublineages of HMPV in India are B1, B2, A2b and A2c.
objectiveA retrospective study was conducted to determine the circulating genotypes of HMPV among SARI cases from January 2016 to December 2018. MATERIALS AND
methodsPositive throat swab samples were confirmed with real-time RT-PCR. Subsequently, these samples were analysed using semi-nested conventional RT-PCR targeting the G gene, followed by sequencing and phylogenetic analysis. Clinical data analysis was also performed using SPSS 15.0 software.
resultsAll 20 samples from the SARI cases were classified under the A2c sublineage of HMPV. Phylogenetic analysis indicated that these strains were genetically related to those circulating in Japan, China, and Croatia. Among the samples, ten showed 111-nucleotide duplications, while the other ten had 180-nucleotide duplications.
conclusionClinical analysis showed that four cases had coinfections with other pathogens. Our extensive analysis of patient samples determined that HMPV, especially the A2c genotype, significantly contributed to SARI cases within our study population, which signifies the importance of considering HMPV as a probable aetiological agent when investigating SARI outbreaks.
