3-(9H-Carbazol-9-yl)-2H-chromen-2-one.
Article in Acta crystallographica. Section E, Structure reports online, 2011. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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.
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 title compound, C(21)H(13)NO(2), was prepared as an example of a new synthesis of carbazoles from a cyclic dibenzo-iodo-lium salt via a twofold Pd-catalysed aryl-ation of a primary amine. The two essentially planar π-subsystems [maximum deviations from the mean square plane of 0.038 (2) Å in the carbazole and 0.059 (2) Å in the coumarine unit] open a dihedral angle of 63.05 (4)°. Two mol-ecules form a centrosymmetrical pair connected via π-π inter-actions between the pyrrole and pyrone rings [centroid-centroid distance = 3.882 (1) Å] and one benzene of the carbazole and the pyrone unit [centroid-centroid distance 3.824 (1) Å]. The lattice is stabilized by C-H⋯O bridging to both coumarin O atoms.
