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

Although core mechanisms and machinery of premRNA splicing are conserved from yeast to human, the details of intron recognition often differ, even between closely related organisms. For example, genes from the pufferfish Fugu rubripes generally contain one or more introns that are not properly spliced in mouse cells. Exploiting available genome sequence data, a battery of sequence analysis techniques was used to reach several conclusions about the organization and evolution of splicing regulatory elements in vertebrate genes. The classical splice site and putative branch site signals are completely conserved across the vertebrates studied (human, mouse, pufferfish, and zebrafish), and exonic splicing enhancers also appear broadly conserved in vertebrates. However, another class of splicing regulatory elements, the intronic splicing enhancers, appears to differ substantially between mammals and fish, with G triples (GGG) very abundant in mammalian introns but comparatively rare in fish. Conversely, short repeats of AC and GT are predicted to function as intronic splicing enhancers in fish but are not enriched in mammalian introns. Consistent with this pattern, exonic splicing enhancer-binding SR proteins are highly conserved across all vertebrates, whereas heterogeneous nuclear ribonucleoproteins, which bind many intronic sequences, vary in domain structure and even presence/absence between mammals and fish. Exploiting differences in intronic sequence composition, a statistical model was developed to predict the splicing phenotype of Fugu introns in mammalian systems and was used to engineer the spliceability of a Fugu intron in human cells by insertion of specific sequences, thereby rescuing splicing in human cells.
