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 14-3-3 protein family is a family of regulatory proteins involved in diverse cellular processes. The presence of 14-3-3 isoforms and the diversity of cellular processes regulated by 14-3-3 isoforms suggest functional specificity of the isoforms. In this study, we report the identification and characterization of a new isoform of the rainbow trout 14-3-3E1 gene generated by alternative splicing. The new isoform contains an insertion of 48 nucleotides (from intron 5) in the coding region of 14-3-3E1 which results in the introduction of a premature stop codon between exon 5 and exon 6. Thus, the alternatively spliced form of 14-3-3E1 (14-3-3E1DeltaC17) lacks 17 amino acid residues at the C terminus encoded by the last exon (exon 6). Reverse-transcription polymerase chain reaction analysis revealed that the wild-type 14-3-3E1 (14-3-3E1wt) is ubiquitously expressed, while 14-3-3E1DeltaC17 shows tissue-specific as well as stage-specific expression during ovarian development and early embryogenesis. Analysis by yeast two-hybrid system demonstrated that 14-3-3E1Delta17 interacts with a number of proteins including ATP synthase, ankyrin repeat domain 13b, cytochrome c subunit VIa, cytochrome c subunit VIb, 60S ribosomal protein L34, solute carrier family 17 member 6 (SLC17A6), troponin I, and an unknown protein. Although all of these proteins except for SLC17A6 also interact with 14-3-3E1wt, 14-3-3E1Delta17 appears to have higher binding affinity with these proteins than 14-3-3E1wt. These findings suggest that alternative splicing affects the function and tissue-specific expression of 14-3-3E1.
