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

RNAi knockdown by using shRNA expression plasmids is widely used to determine the function of individual genes in mammals. Here we developed a simple method to create an IR DNA in a U6 small nuclear RNA promoter-based parent vector using a single-stranded IR DNA with short hairpin structure and Bst DNA polymerase. Furthermore, we demonstrated that the shRNA expression plasmids constructed by our method effectively induced target-specific RNAi in the silkworm cell line. We also found that sequence preference in the silkworm cell line was much lower than in mammalian cells and shRNA-induced RNAi was influenced by the length of the stem region.
