Genomic Surveillance of Human Metapneumovirus in the United States, 2010-2025.
Article in The Journal of infectious diseases, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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 significant cause of acute respiratory illness in both children and adults, yet its genomic epidemiology remains understudied compared to other respiratory viruses.
methodsHybrid capture and whole-genome sequencing were performed on 616 HMPV-positive specimens from 2 cohorts: the household-based HIVE study (2010-2022) in Michigan and the multicenter IVY network (2022-2025) of hospitalized adults. Consensus sequences were generated using IRMA, clades were annotated using Nextclade, and phylogenetic trees were constructed separately for HMPV-A and HMPV-B using IQ-TREE and TreeTime. Analysis of selection by dN/dS was performed using SLAC.
resultsWe obtained complete genomes from 325 specimens. Our analyses revealed the continued predominance of the A2.2.2 clade and little geographic structure in the United States. Genomic diversity was highest in the glycoprotein (G); we identified a shift from variants bearing the 180nt duplication to ones with a 111nt duplication. Phylogenetic analyses supported the duplication-deletion model for the origin of the duplications. The conserved fusion (F) protein showed limited antigenic variation and low rates of nonsynonymous substitutions.
conclusionsThese findings underscore the utility of enhanced genomic surveillance for understanding HMPV evolution and informing vaccine development. There was little genomic diversity in vaccine-targeted epitopes.
