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

Ipecac alkaloids are medicinal monoterpenoid-derived tetrahydroisoquinoline alkaloids found in two distantly related plants: Carapichea ipecacuanha (Gentianales) and Alangium salviifolium (Cornales). Here we provide evidence suggesting that both plants initiate ipecac alkaloid biosynthesis through a nonenzymatic Pictet-Spengler reaction and we elucidate the biosynthetic fate of both the 1R and 1S stereoisomers that are produced in this nonstereoselective reaction. Although the biosynthesis of the 1S-derived protoemetine proceeds according to the same chemical logic in both species, each plant uses a distinct monoterpene precursor. Phylogenetic analyses show examples of independent pathway evolution through parallel and convergently evolved enzymes. This work provides insight into how nature can capitalize on highly reactive starting substrates and the manner in which multistep pathways can arise and lays the foundation for metabolic engineering of these important medicinal compounds.
