Host factors in parainfluenza virus replication: from entry to innate immunity evasion.
Review in Frontiers in immunology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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 parainfluenza viruses (HPIVs)are significant pathogens responsible for acute respiratory infections in infants, the elderly, and immunocompromised individuals. Among children under five, HPIVs are the second most common viral cause of acute lower respiratory tract infections (ALRIs), surpassed only by respiratory syncytial virus (RSV). Despite their significant health impact, there are currently no licensed vaccines or specific antiviral treatments for HPIV infection. Recent advances in functional genomics, including CRISPR-Cas9 screening, cDNA library screening, and multi-omics approaches, have enabled the systematic identification of host factors essential at different stages of HPIVs infections. This review aims to systematically summarize the latest evidence on host factors that influence viral entry, replication, assembly, and release, as well as those involved in evasion of innate immunity. Importantly, we contextualize the mechanisms of these host factors within the broader network of virus-host interactions. By integrating these insights, we aim to provide a strong mechanistic foundation for understanding HPIV pathogenesis to accelerate the development of innovative host-directed therapies(HDTs).
