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

Objectives: Human metapneumovirus (hMPV) is recognized as a significant cause of acute respiratory infections among infants under 5 years of age. Methods: Nasal swabs collected from January 2021 to June 2024 were screened to detect hMPV using reverse transcription-quantitative polymerase chain reaction. Furthermore, representative positive samples were sequenced and subjected to phylogenetic analysis. Results: Of 4519 samples tested, 113 were positive for hMPV. Notably, an outbreak occurred between November 2022 and March 2023, where 56 of 583 (9.6%) patients tested positive. Analysis of the outbreak samples revealed that majority (6.3%) of cases occurred in December and January. hMPV infection was more prevalent in less than 1 year, with 29 (67%) patients with a history of wheezing and 3 (6.9%) with seizures. On the genetic analysis of F protein, 37 samples identified two genotypes as A and B, with subclusters of 29 (85.29%) samples to A2.1, 1 (2.94%) to A2.2.1, and 4 (11.76%) to A2.2.2 within genotype A and one sample clustered with B1 and 2 samples to B2 within genotype B. Conclusions: The study underscores the significant prevalence and genetic diversity of hMPV in children in Puducherry, India. Notably, the identification of novel A2.2.1 and A2.2.2 lineages highlights the evolving nature of hMPV.
