Article in Inorganic chemistry, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
We report the synthesis of a series of dinuclear nickel complexes based on triphenylimidazole-derived salen-type ligands bearing different substituents on the phenyl rings. These complexes were applied as single-component catalysts for the copolymerization of CO2 and alicyclic epoxides. All dinuclear Ni complexes exhibited high catalytic activity and excellent selectivity for the alternating copolymerization of CO2 and cyclohexene oxide (CHO). Among them, the methoxy-substituted bis(acetate) and dichloride complexes 2 and 6 showed the outstanding performance, achieving turnover frequencies (TOFs) exceeding 2000 h-1 and turnover numbers (TONs) over 9000. Notably, the dichloride complex 6 also enabled terpolymerization of different alicyclic epoxides, affording CO2-based polycarbonates bearing vinyl or acrylate functionalities. Kinetic analysis suggests that the copolymerization follows first-order dependence on both complex 6 and CHO concentrations.
