Phosphatidylserine-Specific Phospholipase A1 is the Critical Bridge for Hepatitis C Virus Assembly.
Article in Virologica Sinica, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
The phosphatidylserine-specific phospholipase A1 (PLA1A) is an essential host factor in hepatitis C virus (HCV) assembly. In this study, we mapped the E2, NS2 and NS5A involved in PLA1A interaction to their lumenal domains and membranous parts, through which they form oligomeric protein complexes to participate in HCV assembly. Multiple regions of PLA1A were involved in their interaction and complex formation. Furthermore, the results represented structures with PLA1A and E2 in closer proximity than NS2 and NS5A, and strongly suggest PLA1A-E2's physical interaction in cells. Meanwhile, we mapped the NS5A sequence which participated in PLA1A interaction with the C-terminus of domain 1. Interestingly, these amino acids in the sequence are also essential for viral RNA replication. Further experiments revealed that these four proteins interact with each other. Moreover, PLA1A expression levels were elevated in livers from HCV-infected patients. In conclusion, we exposed the structural determinants of PLA1A, E2, NS2 and NS5A proteins which were important for HCV assembly and provided a detailed characterization of PLA1A in HCV assembly.
