1H-ENDOR evidence for a hydrogen-bonding interaction that modulates the reactivity of a nonheme Fe(IV)═O unit.
Article in Inorganic chemistry, 2012. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
We report that a novel use of 35 GHz (1)H-ENDOR spectroscopy establishes the presence in 1 of an Fe(IV)═O···H-O-Fe(III) hydrogen bond predicted by density functional theory computations to generate a six-membered-ring core for 1. The hydrogen bond rationalizes the difference in the C-H bond cleavage reactivity between 1 and 4(OCH(3)) (where a CH(3)O group has replaced the HO on the Fe(III) site). This result substantiates the seemingly paradoxical conclusion that the nonheme Fe(IV)═O unit of 1 not only has the electrophilic character required for H-atom abstraction but also retains sufficient nucleophilic character to accept a hydrogen bond from the Fe(III)-OH unit.
