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.

Abstract

backgroundDifferent strains of influenza virus are affecting a large number of people worldwide. Many synthetic antiviral medicines are available for influenza virus in the market. But still there is a need for the development of universal drugs against these strains of influenza virus.

methodsFor this purpose conserved residues within the influenza virus nucleoprotein have been retrieved. The drugs, previously known to have antiviral properties, were screened to identify the best candidate universal drug against Influenza virus strains. Compounds from leaf extracts of neem, were also screened to identify the natural drugs without side effects.

resultMolecular docking identified three potential compounds (Nimbaflavone, Rutin, and Hyperoside) having perfect binding with reported conserved residues (ASP302, SER50) of influenza virus nucleoprotein that is involved in the binding of drugs. Further analysis showed Hyperoside as a universal drug against various influenza strains. Some chemical drugs were also evaluated through screening against nucleoprotein. The results showed six drugs (OMS, CBX, LGH, Naproxen, BMS-883559, and BMS-885838) which were interacting with same conserved residues (ASP302, TYR52, SER50, GLY288, SER376, and ARG99) as were found in the case of neem phytochemicals. Hyperoside from neem leaf extract along with drugs LGH, Naproxen, BMS-885838, and BMS-883559 showed best interactions with conserved residues of nucleoprotein.

conclusionThe compound Hyperoside from neem leaf extract along with drugs LGH, Naproxen, BMS-885838, and BMS-883559 showed best interactions with conserved residues of nucleoprotein. So these compounds have been identified for their potential against influenza strains to be utilized as a universal drug.
