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

Enantiomerically enriched α-amino acids and their derivatives are important building blocks, widely used in the pharmaceutical industry, drug research, and materials science. Therefore, the development of straightforward and versatile synthetic methods remains highly desirable. Herein, we disclose a photochemical enantioselective addition of alkyl radicals to α-imino esters, mediated by a chiral-at-metal rhodium catalyst under continuous flow conditions. This strategy provides rapid and direct access to enantioenriched derivatives of both natural and unnatural α-amino acids, achieving yields of up to 75% and enantiomeric ratios of up to 1:99.
