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

We have used homologous recombination to disrupt the nuclear gene NIT8 in Chlamydomonas reinhardtii. This is the first report of targeted gene disruption of an endogenous locus in C. reinhardtii and only the second for a photosynthetic eukaryote. NIT8 encodes a protein necessary for nitrate and nitrite assimilation by C. reinhardtii. A disruption vector was constructed by placing the CRY1-1 selectable marker gene, which confers emetine resistance, within the NIT8 coding region. nit8 mutants are unable to grow on nitrate as their sole nitrogen source (Nit-) and are resistant to killing by chlorate. One of 2,000 transformants obtained after selection on emetine-chlorate medium contained a homologous insertion of five copies of the disruption plasmid into the NIT8 gene, producing an emetine-resistant, chlorate-resistant Nit- phenotype. The mutant phenotype was rescued by the wild-type NIT8 gene upon transformation. Seven other mutations at the nit8 locus, presumably resulting from homologous recombination with the disruption plasmid, were identified but were shown to be accompanied by deletions of the surrounding genomic region.
