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
In order to examine the effect of GRIM19 on colon cancer cell SW480, the recombinant adenovirus carrying GRIM19 gene was constructed and transfected into SW480 cells. GRIM19 cDNA was amplified by PCR with the template pcxn2-GRIM19 and cloned into the shuttle plasmid pAdTrack-CMV. The plasmid pAdTrack-CMV-GRIM19 was linearized by PmeI and homologously recombined with bone plasmid pAdEasy-1 in BJ5183, followed by identification by enzyme digestion. After transfection of linearized pAd-GRIM19 with PacI into HEK293 cells, Ad-GRIM19 was obtained and amplified by 3 circles. SW480 cells were infected with Ad-GRIM19. The apoptosis rate was detected by flow cytometry. Agarose electrophoresis revealed the bands of recombinant plasmids identified by enzyme digestion were in the right range corresponding with expectation. Under the fluorescent microscopy, the package of Ad-GRIM19 in HEK293 cells and the expression of Ad-GRIM19 in SW480 cells were observed. The transfection of Ad-GRIM19 into SW480 cells increased the apoptosis rate of SW480 cells as compared with controls. It was concluded that Ad-GRIM19 was successfully constructed and the overexpression of GRIM19 in colon cancer cell lines could promote the apoptotic cell death.
