1 · What the graph read from it

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.

2 · The registry

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) mediated by small-interfering RNAs (siRNAs) is a highly effective gene-silencing mechanism with great potential for gene-therapeutic applications. siRNA agents also exert non-target-related biological effects and toxicities, including immune-system stimulation. Specifically, siRNA synthesized from the T7 RNA polymerase system triggers a potent induction of type-I interferon (IFN) in a variety of cells. Single-stranded RNA also stimulates innate cytokine responses in mammals. We found that pppGn (n = 2,3) associated with the 5'-end of the short-hairpin RNA (shRNA) from the T7 RNA polymerase system did not induce detectable amounts of IFN. The residual amount of guanine associated with the 5'-end and hairpin structures of the transcript was proportional to the reduction of the IFN response. Here we describe a T7 pppGn (n = 2,3) shRNA synthesis that does not induce the IFN response, and maintains the full efficacy of siRNA.
