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

Active aspartic proteinase is isolated from Brassica napus seeds and the peptide sequence is used to generate primers for PCR. We present here cDNA and genomic clones for aspartic proteinases from the closely related Brassicaceae Arabidopsis thaliana and Brassica napus. The Arabidopsis cDNA represents a single gene, while Brassica has at least 4 genes. Like other plant aspartic proteases, the two Brassicaceae enzymes contain an extra protein domain of about 100 amino acids relative to the mammalian forms. The intron/exon arrangement in the Brassica genomic clone is significantly different from that in mammalian genes. As the proteinase is isolated from seeds, the same tissue where 2S albumins are processed, this implies expression of one of the aspartic proteinase genes there.
