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
objectiveTo investigate the effect of interference of CTPS gene on toosendanin-induced apoptosis of gastric cancer MKN-45 cells.
methodsBioinformatic analysis was used to analyze CTPS gene expression in human gastric cancer tissues and the overall survival of gastric cancer patients with high CTPS gene expression. Human gastric cancer MKN-45 cells were transfected with a short hairpin interfering RNA targeting CTPS gene, and 48 h later, qRT-PCR and Western blotting were used to detect cellular expression CTPS at both the mRNA and protein levels. MKN-45 cells with CTPS knockdown were treated with 80 nmol/L toosendanin for 48 h, and the cell viability was assessed with MTT assay; the cell morphology was observed using laser confocal microscope, and the expression of γH2AX was detected with immunofluorescence assay.
resultsBioinformatic analysis suggested that CTPS was highly expressed in human gastric cancer tissues, and gastric cancer patients with high CTPS gene expression had a shorter overall survival. MKN-45 cells transfected with Sh-CTPS interference vector showed significantly lowered cell survival rate (
conclusionInterference of CTPS gene can promote TSN-induced apoptosis of gastric cancer MKN-45 cells.
