1 · What the graph read from it

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.

2 · The registry

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 first steroidogenic enzyme, cytochrome P450-side-chain-cleavage (SCC), requires electron transport chain (ETC) complexes III and IV to initiate steroid metabolic processes for mammalian survival. ETC complex II, containing succinate dehydrogenase (quinone), acts with the TCA cycle and has no proton pumping capacity. We show that complex II is required for SCC activation through the proton pump, generating an intermediate state for addition of phosphate by succinate. Phosphate anions in the presence of succinate form a stable mitochondrial complex with higher enthalpy (-ΔH) and enhanced activity. Inhibition of succinate action prevents SCC processing at the intermediate state and ablates activity and mitochondrial protein network. This is the first report directly showing that a protein intermediate state is activated by succinate, facilitating the ETC complex II to interact with complexes III and IV for continued mitochondrial metabolic process, suggesting complex II is essential for steroid metabolism regulation.
