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 efficient construction of boron stereogenic centers alongside axial chirality remains a significant synthetic challenge, particularly under one-pot conditions. Herein, we report a cobalt/Salox-catalyzed enantioselective annulation strategy that enables the simultaneous formation of B-stereogenic frameworks and a C─N chiral axis via C─H and N─H annulation of arylamides with dialkynylborons. This protocol achieves asymmetric desymmetrization at boron along with effective diastereocontrol on the C─N axis under mild conditions. A wide range of aryl amides and alkynes are well tolerated, delivering structurally diverse products in good yields with consistently high diastereo- and enantioselectivities. Mechanistic studies, including control experiments and isotope labelling, provide insight into the reaction pathway and the origin of stereocontrol. The resulting chiral boron-containing compounds exhibit notable fluorescence, and their photophysical properties suggest potential utility in optoelectronic applications.
