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

The Del1 mutant of the green alga Chlamydomonas reinhardtii with a defined deletion in the chloroplast encoded psbA gene is unable to grow photoautotrophically. We show here that this mutant can be transformed with PCR-generated psbA fragments of varying length to yield photosynthetically growing colonies. PCR fragments need not be purified but can be directly precipitated from the amplification reaction onto tungsten particles, allowing fast and efficient mutagenesis experiments. Flanking regions bordering the deletion breakpoints have been systematically shortened from both sides. The shortest fragment giving rise to significant numbers of transformants contains about 50 bp upstream and 120 bp downstream of the deletion breakpoint. This technique greatly simplifies comprehensive structure-function analyses of the D1 protein in Chlamydomonas, but could perhaps be adapted to other chloroplast genes in this or other organisms as well.
