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
Pre-mRNA splicing is executed by the spliceosome, a complex of small nuclear RNAs (snRNAs) and numerous proteins. One such protein, 15.5K/Snu13p, is associated with the spliceosomal U4/U6.U5 tri-snRNP and box C/D small nucleolar ribonucleoprotein particles (snoRNPs), which act during preribosomal RNA (rRNA) processing. As such, it is the first splicing factor to be identified in two functionally distinct particles. 15.5K binds to an internal helix-bulge-helix (K-turn) structure in the U4 snRNA and two such structures in the U3 snoRNA. Previous work has concentrated on the structural basis of the interaction of 15.5K with the RNAs and has been carried out in vitro. Here we present a functional analysis of Snu13p in vivo, using a galactose inducible SNU13 strain to investigate the basis of three lethal mutations in Saccharomyces cerevisiae. Two are point mutations that map to the RNA-binding domain, and the third is a C-terminal deletion. These mutations result in accumulation of unspliced pre-mRNA, confirming a role for Snu13p in pre-mRNA splicing. In addition, these mutants also display rRNA processing defects that are variable in nature. Analysis of one mutant in the RNA-binding domain reveals a reduction in the levels of the U4 snRNA, U6 snRNA, and box C/D snoRNAs, but not H/ACA snoRNAs, supporting a role for Snu13p in accumulation and/or maintenance of specific RNAs. The mutations in the RNA-binding domain exhibit differential binding to the U4 snRNA and U3 snoRNA in vitro, suggesting that there are differences in the mode of interaction of Snu13p with these two RNAs.
