Mutations in the C-terminus of HBoV NS1 affect the function of NP1.
Article in Scientific reports, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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 bocavirus 1 (HBoV1) is an autonomous parvovirus in the Bocaparvovirus genus. The multifunctional nuclear protein NP1 is involved in viral replication. In the present study, we found that the mutations in the C-terminus of NS1 affected NP1 function in viral replication. Knocking out NP1 expression in the recombinant infectious clone, on which the C-terminus of NS1 was mutated based on the clinical samples from nasopharyngeal aspirates, resulted in different degrees of decreased replication. The result suggested that NP1 facilitated the replication of viral genome but was not necessary, which is different from the minute virus of canines, where NP1 is essential for viral replication. Further studies showed that clinical mutations in the NP1 region did not affect viral genome replication, and UP1 promoted viral DNA replication. Our results suggested that the C-terminus of NS1 is important for viral replication and may be a target for regulating the replication of the viral genome.
