1 · What the graph read from it

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.

2 · The registry

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

Emerging viruses in the paramyxovirus genus Henipavirus evade host antiviral responses via protein interactions between the viral V and W proteins and cellular STAT1 and STAT2 and the cytosolic RNA sensor MDA5. Polo-like kinase (PLK1) is identified as being an additional cellular partner that can bind to Nipah virus P, V, and W proteins. For both Nipah virus and Hendra virus, contact between the V protein and the PLK1 polo box domain is required for V protein phosphorylation. Results indicate that PLK1 is engaged by Nipah virus V protein amino acids 100 to 160, previously identified as being the STAT1 binding domain responsible for host interferon (IFN) signaling evasion, via a Thr-Ser-Ser-Pro motif surrounding residue 130. A distinct Ser-Thr-Pro motif surrounding residue 199 mediates the PLK1 interaction with Hendra virus V protein. Select mutations in the motif surrounding residue 130 also influenced STAT1 binding and innate immune interference, and data indicate that the V:PLK1 and V:STAT complexes are V mediated yet independent of one another. The effects of STAT1/PLK1 binding motif mutations on the function the Nipah virus P protein in directing RNA synthesis were tested. Remarkably, mutations that selectively disrupt the STAT or PLK1 interaction site have no effects on Nipah virus P protein-mediated viral RNA synthesis. Therefore, mutations targeting V protein-mediated IFN evasion will not alter the RNA synthetic capacity of the virus, supporting an attenuation strategy based on disrupting host protein interactions.
