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 semipinacol rearrangement comprises a valuable class of synthetic organic transformations that provide access to useful molecular scaffolds via C-C bond cleavage and formation. Naturally occurring semipinacolases have thus far been limited to examples in alkaloid or polyketide biosynthesis, and the only new-to-nature semipinacolase was reported based on Brønsted acid catalysis with limited substrate scope. Herein, we report that flavin-dependent halogenases (FDHs) can catalyze enantioselective halogenative semipinacol rearrangement of prochiral allylic alcohols. This biocatalytic platform exhibits a broad substrate scope, affording chiral ketones bearing quaternary stereocenters with a high enantioselectivity. The reaction system displays a
