Cryoradiolysis of oxygenated cytochrome P450 17A1 with lyase substrates generates expected products.
Article in Journal of inorganic biochemistry, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
When subjected to γ-irradiation at cryogenic temperatures the oxygenated complexes of Cytochrome P450 CYP17A1 (CYP17A1) bound with either of the lyase substrates, 17α-Hydroxypregnenolone (17-OH PREG) or 17α-Hydroxyprogesterone (17-OH PROG) are shown to generate the corresponding lyase products, dehydroepiandrosterone (DHEA) and androstenedione (AD) respectively. The current study uses gas chromatography-mass spectrometry (GC/MS) to document the presence of the initial substrates and products in extracts of the processed samples. A rapid and efficient method for the simultaneous determination of residual substrate and products by GC/MS is described without derivatization of the products. It is also shown that no lyase products were detected for similarly treated control samples containing no nanodisc associated CYP17 enzyme, demonstrating that the product is formed during the enzymatic reaction and not by GC/MS conditions, nor the conditions produced by the cryoradiolysis process.
