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
The rat beta-tropomyosin (beta-TM) gene encodes both skeletal muscle beta-TM mRNA and nonmuscle TM-1 mRNA via alternative RNA splicing. This gene contains eleven exons: exons 1-5, 8, and 9 are common to both mRNAs; exons 6 and 11 are used in fibroblasts as well as in smooth muscle, whereas exons 7 and 10 are used in skeletal muscle. Previously we demonstrated that utilization of the 3' splice site of exon 7 is blocked in nonmuscle cells. In this study, we use both in vitro and in vivo methods to investigate the regulation of the 5' splice site of exon 7 in nonmuscle cells. The 5' splice site of exon 7 is used efficiently in the absence of flanking sequences, but its utilization is suppressed almost completely when the upstream exon 6 and intron 6 are present. The suppression of the 5' splice site of exon 7 does not result from the sequences at the 3' end of intron 6 that block the use of the 3' splice site of exon 7. However, mutating two conserved nucleotides GU at the 5' splice site of exon 6 results in the efficient use of the 5' splice site of exon 7. In addition, a mutation that changes the 5' splice site of exon 7 to the consensus U1 snRNA binding site strongly stimulates the splicing of exon 7 to the downstream common exon 8. Collectively, these studies demonstrate that 5' splice site competition is responsible, in part, for the suppression of exon 7 usage in nonmuscle cells.
