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

objectiveGuayule (Parthenium argentatum) is a rubber producing plant. Genetic engineering of guayule to improve natural rubber content requires the use of promoters functional in stem tissues where most of guayule natural rubber is produced.

resultsWe isolated a promoter region from a gene coding the Small Rubber Particle Protein 1. Transgenic guayule lines expressing the Small Rubber Particle Protein 1 promoter fused to β-glucuronidase reporter gene were developed. The promoter, active in leaf, stem and root tissues drives significant levels of transgene expression, especially in the stem tissue. The isolated Small Rubber Particle Protein 1 promoter is a new molecular element in the toolbox available for guayule improvement through genetic engineering strategies.
