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

Described here is an example of organocatalytic enantioselective formal O-H bond insertion of α-carbonyl sulfur ylides, providing efficient access to highly enantioenriched ketones bearing a tertiary α-oxygenated stereocenter. This metal-free approach is complementary to the well-established metal-based diazo carbonyl chemistry, which has gained broad success for esters but not for ketones. The proper choice of a chiral thiourea catalyst in combination with
