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

Pod development in oilseed rape (Brassica napus) culminates in a process known as dehiscence (shatter) which can result in the loss of seed before the crop is harvested. In order to investigate the biochemical and the genetic basis controlling this process, a cDNA library was constructed from the dehiscence zone of developing pods. This resulted in the isolation of a cDNA clone (SAC51). The mRNA encoded by SAC51 had a transcript size of ca. 700 nucleotides and was found, by northern analysis, to accumulate preferentially in the dehiscence zone of the pod and in no other part of the plant analysed. The predicted polypeptide is rich in the amino acids proline (14.2%) and leucine (14.2%). The sequence of the polypeptide has more than 40% amino acid sequence identity with polypeptides isolated from carrot embryos, maize roots, soybean seeds and young tomato fruit. The function of these proteins is unknown. Genomic Southern analysis suggests that SAC51 is encoded by a single gene or small gene family. The role of the peptide in the development of pods of oilseed rape is discussed.
