Dynamics and Mechanism of Binding of Androstenedione to Membrane-Associated Aromatase.
Article in Biochemistry, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 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
Aromatase (CYP19A1) catalyzes the synthesis of estrogens from androgens and is an invaluable target of pharmacotherapy for estrogen-dependent cancers. CYP19A1 is also one of the most primordial human CYPs and, to the extent that its fundamental dynamics are conserved, is highly relevant to understanding those of the more recently evolved and promiscuous enzymes. A complementary approach employing molecular dynamics simulations and hydrogen-deuterium exchange mass spectrometry (HDX-MS) was employed to interrogate the changes in CYP19A1 dynamics coupled to binding androstenedione (ASD). Gaussian-accelerated molecular dynamics and HDX-MS agree that ASD globally suppresses CYP19A1 dynamics. Bimodal HDX patterns of the B'-C loop potentially arising from at least two conformations are present in free 19A1 only, supporting the possibility that conformational selection is operative. Random-acceleration molecular dynamics and adaptive biasing force simulations illuminate ASD's binding pathway, predicting ASD capture in the lipid headgroups and a pathway to the active site shielded from solvent. Intriguingly, the predicted access channel in 19A1 aligns well with the steroid binding sites of other human sterol-oxidizing CYPs.
