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
BACKGROUND Small nuclear ribonucleoproteins (snRNPs) complexes of protein and noncoding RNA accumulate in the cell nucleus and catalyze pre-mRNA splicing to form the spliceosome. This study aimed to investigate the role of the spliceosome, splicing factor 3b subunit 1 (SF3B1), in AGS and MKN28 human gastric cancer cells in vitro, including gene knockdown with small interfering RNA (siRNA), and the use of the selective mRNA splicing inhibitor of SF3B1, pladienolide B. MATERIAL AND METHODS In AGS and MKN28 human gastric cancer cells, SF3B1expression was inhibited with siRNA and pladienolide B. Following SF3B1 inhibition, the Cell Counting Kit-8 (CCK-8) assay measured cell proliferation, and flow cytometry was used to investigate cell apoptosis and cell cycle arrest. The downstream HOXA10 and AKT pathways were studied by quantitative reverse transcription-polymerase chain reaction (qRT-PCR) and Western blot. The presence of alternative splicing, or differential splicing, of single-gene coding for multiple proteins, was analyzed using The Cancer Genome Atlas (TCGA) SpliceSeq. RESULTS Inhibition of SF3B1 reduced the proliferation rate of AGS and MKN28 human gastric cancer cells by inducing apoptosis and G2/M phase arrest. SF3B1 knockdown resulted in reduced homeobox A10 (HOXA10) mRNA expression and expression of long noncoding RNA (lncRNA) isoforms of HOXA10 (exons 1 and 3) and HOXA10 (exons 2 and 3). SF3B1 inhibition increased PTEN levels and reduced AKT protein phosphorylation. CONCLUSIONS In AGS and MKN28 human gastric cancer cells in vitro, inhibition of SF3B1 reduced cell proliferation, induced apoptosis, and resulted in cell cycle arrest by regulating HOXA10 splicing.
