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

Antisense suppression is a powerful tool to analyze gene function. In this study, we show that antisense RNA suppressed the expression of a target gene in the unicellular red alga, Cyanidioschyzon merolae. In this study, the antisense strand of the catalase gene was cloned and inserted into an expression vector upstream of the GFP gene. This plasmid was introduced into C. merolae cells using a polyethylene glycol-mediated transformation protocol. Using the expression of GFP as a marker of transformed cells, the expression of catalase was examined by immunocytochemistry. Decreased expression of catalase was observed in cells that were transformed with the antisense strand of the catalase gene. These results indicate the utility of this antisense suppression system.
