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

Ansalactam A is an ansa macrolide natural product that contains a densely functionalized spiro-γ-lactam core containing three contiguous stereocenters. This unusual motif distinguishes it from other members of this family and represents a significant synthetic challenge. Herein, we report the development of a stereoselective formal [3+2] cycloaddition reaction for the construction of this key spiro-γ-lactam motif for the first time, thereby enabling access to the northern domain of ansalactam A.
