Mutant allele of rna14 in fission yeast affects pre-mRNA splicing.
Article in Journal of genetics, 2016. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Spliceosome and 3'-end processing complexes are necessary for the precursor mRNA (pre-mRNA) maturation. Spliceosome complex removes noncoding introns, while 3'-end processing involves in cleavage and addition of poly(A) tails to the nascent transcript. Rna14 protein in budding yeast has been implicated in cleavage and polyadenylation of mRNA in the nucleus but their role in the pre-mRNA splicing has not been studied. Here, we report the isolation of a mutant allele of rna14 in fission yeast, Schizosaccharomyces pombe that exhibits reduction in protein level of Chk1 at the nonpermissive temperature, primarily due to the defects in posttranscriptional processing. Reverse transcriptase-polymerase chain reaction analysis reveals defective splicing of the chk1(+) transcript at the nonpermissive temperature. Apart from chk1(+), the splicing of some other genes were also found to be defective at the nonpermissive temperature suggesting that Rna14 might be involved in pre-mRNA splicing. Subsequently, genetic interaction of Rna14 with prp1 and physical interactions with Prp28 suggest that the Rna14 might be part of a larger protein complex responsible for the pre-mRNA maturation.
