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

Diamond's elementary chiral constituent-skew-tetramantane-features extreme rigidity, stability and a precisely defined geometry, epitomizing the parent structure of a σ-helicene. While skew-tetramantane is naturally occurring in trace fractions in fossil fuels, efforts over several decades towards its selective synthesis remained unfruitful. With the recent advances in photocatalysis and transition metal catalysis to tame radical and carbene species, we have now devised a targeted total synthesis of skew-tetramantane by means of a stereoselective adamantalogous cage extension. A first cap attachment was effected by a photocatalytic Giese reaction, while remarkable regio-, diastereo- and enantiocontrol were achieved by an intramolecular C(sp
