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

Analysis of aberrant ribosomal DNA (rDNA) repeats of Bombyx mori resulted in the discovery of a 4.8 kilobase retrotransposable element, Pao. Approximately 40 copies of Pao are present in the genome with most located outside the rDNA units. The complete sequence of one Pao element and partial sequence of four other copies indicated that Pao encodes an 1158 amino acid open-reading frame (ORF). Located within this ORF are domains with sequence similarity to retroviral gag genes, aspartic protease and reverse transcriptase. RNase H and integrase domains were not identified suggesting that the cloned copies were not full-length elements. Pao elements contain long terminal repeats (LTRs) with a central region composed of variable numbers of 46 bp tandem repeats. The variable region appears to correspond to the R region of retroviral LTRs, the region responsible for strand transfer during reverse transcription. Based on a sequence analysis of its reverse transcriptase domain, Pao is most similar to TAS of Ascaris lumbricoides. Pao and TAS represent a subgroup of LTR retrotransposons distinct from the Copia-Ty1 and Gypsy-Ty3 subgroups.
