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

The complexity and versatility of terpene cyclization reactions contribute to the wide variety of functions and properties that terpenoid compounds exhibit in nature. The management of reactive carbocations over the course of the reaction to ultimately arrive at a particular carbon fragment connectivity and stereochemistry is no small feat. Bacteria possess a variety of TSs that generate diverse polycyclic terpene skeletons; however, terpenoids in myxobacteria are especially rare. Here, we report the first mechanistic study of tetraisoquinene biosynthesis from TiqS, a diterpene synthase from
