Resistance-based training improves mitochondrial capacity and redox balance in aging adults, independent of polyphenol supplementation.
Trial report in Redox biology, 2026. 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
Aging is associated with declines in skeletal muscle function, mitochondrial capacity, and changes in redox balance, which collectively contribute to frailty and chronic disease risk. This study investigated the effects of a 12-week resistance training (RT) program combined with a small dose of high-intensity interval training (HIIT), with or without polyphenol supplementation, on mitochondrial respiratory capacity (MRC) and oxidative stress in middle-aged and older adults (55-70 years). Forty-one participants were randomized to receive either a polyphenol supplement or a placebo for 30 days before the training intervention. Following the training intervention, aerobic capacity, lean mass, and strength improved significantly in both groups. Training also increased MRC in the placebo group but not in the polyphenol group, which displayed higher MRC following the supplementation phase, possibly reflecting either a supplement effect or baseline variation. The training resulted in a 20 % decrease in skeletal muscle H
