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
RNA interference (RNAi) can induce gene silencing via two pathways: post-transcriptional gene silencing (PTGS) and transcriptional gene silencing (TGS). The mediators of gene inactivation in both pathways are 21-bp small interfering RNAs (siRNAs) generated from longer double-stranded RNA (dsRNA). PTGS involves siRNA-mediated targeting and degradation of mRNA. However, siRNAs induce TGS via DNA methylation at the targeted promoter. Synthetic siRNAs can induce loss of gene activity comparable to long dsRNA. The limitation of this method is that the transfected synthetic siRNA works for only a few days. In this study, we tested the RNAi response to siRNA (PTGS pathway) by using a plasmid containing an enhanced green fluorescent protein (eGFP) gene as a target as well as a plasmid creates siRNA transcript, in a form of a hairpin, against eGFP gene. To investigate TGS pathway via RNAi, we also used a plasmid creates hairpin siRNA transcript against pgk-1 promoter. The data presented here indicated long-lasting inhibition in expression of eGFP and puromycin genes, both under the control of the murine Pgk-1 promoter. However, Southern blot analysis showed no methylation in pgk-1 promoter.
