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

Black gram (Vigna mungo L.) plants showing yellow mosaic symptoms during 2019-2022 crop seasons were collected randomly from a Dayalbagh field, Agra Region of Uttar Pradesh, India. Total genomic DNA was isolated from the infected leaf samples by the Cetyltrimethylammonium bromide (CTAB) method and subjected to PCR. After viral confirmation, the viral genome was amplified by rolling circle amplification following the standard protocol. The DNA A and DNA B subgenomes were cloned individually as a PstI and BamHI fragment in the pUC18 vector. Positive clones were subjected to DNA sequencing. The results revealed that DNA A and DNA B show the closest nucleotide identity with "mungbean yellow mosaic India virus-[Mungbean], DNA-A, the complete sequence" (GeneBank Accession No AF416742.1) with 98.14% identity, and "mungbean yellow mosaic India virus isolate Mu1-Dholi segment DNA-B, the complete sequence" (GeneBank Accession No MW814723.1) with 97.94% identity, respectively. The new isolate of mungbean yellow mosaic India virus (MYMIV) shows sequence similarity with the coat protein gene of various strains of MYMIV. In the new isolate of MYMIV, a point mutation was observed at the 2036th nucleotide of DNA B, which disrupts the reading frame to introduce a stop codon and thus leading to a decrease in the size of the movement protein gene. In the present study we are reporting the whole genome sequence of the MYMIV Dayalbagh isolate for the first time.
