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
Three novel families of repetitive DNA sequences were molecularly cloned from the Korean field mouse (Apodemus peninsulae) and characterized by chromosome in-situ hybridization and filter hybridization. They were all localized to the centromeric regions of all autosomes and categorized into major satellite DNA, type I minor, and type II minor repetitive sequences. The type II minor repetitive sequence also hybridized interspersedly in the non-centromeric regions. The major satellite DNA sequence, which consisted of 30 bp elements, was organized in tandem arrays and constituted the majority of centromeric heterochromatin. Three families of repetitive sequences hybridized with B chromosomes in different patterns, suggesting that the B chromosomes of A. peninsulae were derived from A chromosomes and that the three repetitive sequences were amplified independently on each B chromosome. The minor repetitive sequences are present in the genomes of the other seven Apodemus species. In contrast, the major satellite DNA sequences that had a low sequence homology are present only in a few species. These results suggest that the major satellite DNA was amplified with base substitution in A. peninsulae after the divergence of the genus Apodemus from the common ancestor and that the B chromosomes of A. peninsulae might have a species-specific origin.
