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

Caenorhabditis elegans is unusual among animals in having a highly conserved octamer sequence at the 3' splice site: UUUU CAG/R. This sequence can bind to the essential heterodimeric splicing factor U2AF, with U2AF65 contacting the U tract and U2AF35 contacting the splice site itself (AG/R). Here we demonstrate a strong correspondence between binding to U2AF of RNA oligonucleotides with variant octamer sequences and the frequency with which such variations occur in splice sites. C. elegans U2AF has a strong preference for the octamer sequence and exerts much of the pressure for 3' splice sites to have the precise UUUUCAG/R sequence. At two positions the splice site has a very strong preference for U even though alternative bases can also bind tightly to U2AF, suggesting that evolution can select against sequences that may have a relatively modest reduction in binding. Although pyrimidines are frequently present at the first base in the exon, U2AF has a very strong bias against them, arguing there is a mechanism to compensate for weakened U2AF binding at this position. Finally, the C in the consensus sequence must remain adjacent to the AG/R rather than to the stretch of U's, suggesting this C is recognized by U2AF35.
