Development and optimization of a direct plaque assay for trypsin-dependent human metapneumovirus strains.
Article in Journal of virological methods, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 11 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
Human metapneumovirus (HMPV) is a non-segmented, negative strand RNA virus belonging to the family Pneumoviridae, previously a subfamily of Paramyxoviridae. It is a leading cause of lower respiratory tract infection in infants, children, and adults with underlying medical conditions. HMPV grows poorly in cell culture and requires trypsin to cleave and mature the virus particles, which adds to the challenge of HMPV research. Currently, an indirect immuno-staining assay is commonly used to titrate HMPV, which is time-consuming and costly. In order to simplify virus quantification for HMPV, a direct plaque assay was developed. By optimizing trypsin concentration and other supplements in the agarose overlay, it was found that HMPV strains from all four subgroups formed clear and countable plaques 5-7 days post-infection. Animal tissue homogenate can also be directly titrated with this assay. Compared with the traditional assay, the direct plaque assay yields similar titer result, but saves time and eliminates the use of antibodies. Potentially, it can also be applied to plaque purification for HMPV clinical isolates. The direct plaque assay will be a valuable tool in HMPV research.
