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
We report the cloning, sequencing and analysis of the major repetitive DNA of soybean (Glycine max). The repeat, SB92, was cloned as several monomers and trimers produced by digestion with XhoI. The deduced consensus sequence of the repeat is 92 base pairs long. Genomic sequences do not fluctuate in length. Their average homology to the consensus sequence is 92%. The consensus of SB92 contains slightly degenerated homologies for several 6-cutters. Therefore, many of them generate a ladder of 92-bp oligomers. The distribution of bands seems to be random, but the occurrence of sites for different 6-cutters varies widely. There is no obvious correlation between the sequences of the neighboring units of SB92 in cloned trimers. Also, there are none of the internal repetitive blocks reported for many satellite DNAs from other species. The SB92 repeat makes up 0.7% of total soybean DNA. This is equivalent to 8×10(4) copies, or 7 megabases. The repeat is organized in giant tandem blocks over 1 Mb in length, and there are fewer blocks than chromosomes. The polymorphism of these blocks is extremely high. The SB92 repeat is present in identical arrangement and number of copies in the ancestral subspecies Glycine soja. There are 10 times fewer copies of the repeat in a related species Vigna unguiculata (cowpea), and no homologies in several other more distant leguminous plants studied.
