Phylogenetic analysis of Rice tungro bacilliform virus ORFs revealed strong correlation between evolution and geographical distribution.

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
A new isolate of Rice tungro bacilliform virus (RTBV) was collected from Chinsura, West Bengal, India. The full genome was sequenced and deposited to GenBank designating the new one as Chinsura isolate. The four open reading frames (ORFs) of the new isolate were compared with those of previously reported 'South-east Asian' (SEA) and 'South Asian' (SA) isolates emphasizing the ORF3, which is the largest and functionally most important gene of RTBV. In the ORFs, Chinsura isolate shared 90.0-100.0% identity at amino acid level with SA isolates, but only 58.76-88.63% identity with SEA isolates for the same. Similarly, the amino acid identity of ORFs between SEA and SA isolates ranged from 58.77 to 88.64, whereas within each group the corresponding value was >96.0%. The phylogenetic analysis based on nucleotide and amino acid sequences of each ORF made two broad clusters of SEA- and SA-types including Chinsura isolate within SA cluster. Moreover, the relative positions and length of functional domains corresponding to movement protein (MP), coat protein (CP), aspartate protease (PR) and reverse transcriptase/ribonuclease H (RT/RNase H) of ORF3 of Chinsura isolate were completely identical with SA isolates. The clustering pattern indicated strong influence of geographical habitat on genomic evolution. Comparison of ORF3 among all the isolates revealed major variations at non-functional regions in between the functional domains and at the hypervariable 3'-terminal end of ORF3, while PR appeared to have evolved differentially in SA isolates expecting further characterization.
