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

Small hairpin RNA (shRNA) is a powerful tool for inhibiting gene expression. One limitation has been that this technique has been used primarily to target a single gene. This protocol expands upon previous methods by describing a knockdown vector that facilitates cloning of multiple shRNAs; this allows targeted knockdown of more than one gene or of a single gene that may otherwise be difficult to knockdown using a single shRNA. The targeted gene(s) can be readily re-expressed by transfecting knockdown cells with a knock-in vector, containing an shRNA-refractive cDNA that will express the protein-of-interest even in the presence of shRNAs. The constructed knockdown and knock-in vectors can be easily used concurrently to assess possible interrelationships between genes, the effects of gene loss on cell function and/or their restoration by replacing targeted genes one at a time. The entire knockdown or knock-in procedure can be completed in approximately 3-4 months.
