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

Neurometabolism is increasingly recognized as a pathogenic contributor to neurodegenerative disease. However, commonly reported mitochondrial functional outcomes (e.g., respiration) often lack specificity with respect to energetic demand, carbon substrate utilization, and key bioenergetic parameters such as mitochondrial membrane potential. To address this limitation, the present study sought to determine whether oxidative phosphorylation conductance differs across brain regions and as a function of carbon substrate. Oxidative phosphorylation conductance was investigated in permeabilized frontal cortex and hippocampus of female and male C57BL/6J mice using pyruvate/malate substrate (PM, supporting complex I) or succinate with rotenone complex-I inhibition (SR, supporting complex II). Both mitochondrial volume (multiphoton microscopy) and abundance (flow cytometry) assessments showed no regional differences (
