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 registryThe 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.

6 · The paper itselfAbstract
Two different families of BN-doped [5]helicenes have been efficiently synthesized through a highly enantioselective, intramolecular, Au-catalyzed alkyne hydroarylation reaction. Key for the success of the method is the use of BINOL-derived cationic phosphonites as ancillary ligands (BINOL: 1,1-bi-2-naphthol). The inversion barriers of the structures obtained have been determined both experimentally and theoretically, and are essentially identical to those reported for non-dopped carbo[5]helicenes of otherwise identical structure. Contrarily, the newly prepared BN-doped helicenes exhibit intensified absorption spectra at long wavelength (
