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

Dodonaea viscosa is known for its rich arsenal of phytochemicals and has been traditionally used as a folk medicine. Decades of research have targeted isolation of the potent bioactives, including the unique clerodane and labdane diterpenoids identified in this plant. Growing interest in these bioactive compounds from D. viscosa Jacq. provides impetus towards elucidation of their biosynthetic pathway to enable the potential for scalable production via synthetic biology. Here a draft nuclear, along with complete chloroplast and mitochondrial, genome sequences for D. viscosa, along with annotation of the nuclear genome, are presented. This enabled discovery and biochemical characterization of two class II diterpene cyclase enzymes, DvCPS and DvKPS, which respectively catalyze the formation of ent-copalyl pyrophosphate and ent-kolavenyl pyrophosphate, precursors to the labdane and clerodane bioactive diterpenoids found in this medicinal herb.
