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

Dragon's blood, the red resin derived from the wounded Dracaena, is a precious traditional medicine used by different culture. Dracaena cochinchinensis is one of the main species of Dracaena, and is the endangered medicinal plants in China. The vulnerable status severely limits the medicinal value and wide application of dragon's blood. Therefore, it's essential to analyze the mechanisms that form dragon's blood in order to increase artificial production. To clarify the mechanisms forming dragon's blood, understanding gene expression in the flavonoid biosynthesis pathway is the foundation. However, reference genes of D. cochinchinensis haven't been analyzed. In this study, expression profiles of seven commonly used housekeeping genes (Actin, α-EF, UBC, β-tubulin, 18S, GAPDH, His) were evaluated by using quantitative real-time PCR combined with the algorithms geNorm, NormFinder, BestKeeper, and RefFinder. On the basis of overall stability ranking, the best reference genes were the combinations β-tubulin +UBC for wounded stems and α-EF +18S + Actin for different organs. Reliability of the recommended reference genes was validated by normalizing relative expression of two key enzyme genes PAL1 and CHI1 in the flavonoid biosynthesis pathway. The results provide a foundation to study gene expression in future research on D. cochinchinensis or other Dracaena.
