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

Carotenoids are isoprenoid lipids found across the tree of life with important implications in oxidative stress adaptations, photosynthetic metabolisms, as well as in membrane dynamics. The canonical view is that C40 carotenoids are synthesized from phytoene and C30 carotenoids from diapophytoene. Squalene is mostly associated with the biosynthesis of polycyclic triterpenes, although there have been suggestions that it could also be involved in the biosynthesis of C30 carotenoids. However, demonstration of the existence of this pathway in nature is lacking. Here, we demonstrate that C30 carotenoids are synthesized from squalene in the Planctomycetes bacteria and that this squalene route to C30 carotenoids is the most widespread in prokaryotes. Using the evolutionary history of carotenoid and squalene amino oxidases, we propose an evolutionary scenario to explain the origin and diversification of the different carotenoid and squalene-related pathways. We show that carotenoid biosynthetic pathways have been constantly transferred and neofunctionalized during prokaryotic evolution. One possible origin of the squalene pathway connects it with the one of C40 carotenoid synthesis of Cyanobacteria. The widespread occurrence of the squalene route to C30 carotenoids in
