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

Type III polyketide synthases (PKSs) have a much simpler three-dimensional architecture compared with their type I and type II counterparts, yet they catalyze iterative polyketide elongation to generate a myriad of products in plants, fungi, and eubacteria. Despite this mechanistic complexity occurring within a single active site, the mechanism by which type III PKSs stabilize and direct their highly reactive keto and enolate intermediates has yet to be fully understood. Here, we report the synthesis and deployment of stable polyketone CoA analogues for each putative intermediate involved in the biphenyl synthase (BIS) mechanism together with three high-resolution crystal structures of each in complex with BIS from
