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
Rice tungro disease is caused by a combination of two viruses: Rice tungro spherical virus and Rice tungro bacilliform virus (RTBV). This study was performed with the objective to decipher the molecular variability and evolution of RTBV isolates present in the tungro-affected states of Indian subcontinent. Phylogenetic analysis based on ORF-I, ORF-II, and ORF-IV sequences showed distinct divergence of Indian RTBV isolates into two groups; one consisted isolates from Hyderabad (Andhra Pradesh), Cuttack (Orissa), and Puducherry and another from West Bengal, Chinsura West Bengal, and Kanyakumari (Tamil Nadu). The results obtained from phylogenetic analysis were further supported with the single nucleotide polymorphisms (SNPs), insertion and deletion (INDELs) and evolutionary distance analysis. In addition, sequence difference count matrix revealed a maximum of 56 (ORF-I), 13 (ORF-II) and 73 (ORF-IV) nucleotides differences among all the Indian RTBV isolates taken in this study. However, at the protein level these differences were not significant as revealed by K (a)/K (s) ratio calculation. Sequence identity at nucleotide and amino acid level was 92-100 % (ORF-I), 96-100 % (ORF-II), 94-100 % (ORF-IV) and 86-100 % (ORF-I), 98-100 % (ORF-II) and 95-100 % (ORF-IV), respectively, among Indian isolates of RTBV. The divergence of RTBV isolates into two independent clusters of Indian and non-Indian was shown with the help of the data obtained from phylogeny, SNPs, and INDELs, evolutionary distance analysis, and conserved motifs analysis. The important role of ORF-I and ORF-IV in RTBV diversification and adaptation to different rice growing regions is also discussed.
