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
To understand the control and regulation of mitochondrial energy metabolism a generalized matrix method of Metabolic Control Analysis has been applied to a computational model of mitochondrial energetics. The computational model of Cortassa et al. (2003) encompasses oxidative phosphorylation, the tricarboxylic acid (TCA) cycle, and ion dynamics across the inner mitochondrial membrane. Control of respiration and ATP synthesis fluxes were found to be distributed among various mitochondrial processes. Control is shared by processes associated with ATP synthesis and ATP/ADP transport, as well as by Ca(2+) dynamics. The analysis of flux control coefficients and response coefficients has led to the notion of control by diffuse loops, that points to the regulatory interactions exerted by processes that are mechanistically only indirectly related with each other. The approach we have utilized demonstrates how properties of integrated systems may be understood through applications of computational modeling and control analysis.
