Muscle ubiquinone in healthy physically active males.
Article in Molecular and cellular biochemistry, 1996. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
Thirty-five (35) healthy physically active males had muscle biopsies taken from their vastus lateralis muscle to analyze for ubiquinone (vitamin Q, UQ), oxidative (muscle fiber types expressed as %ST and citrate synthase activity, CS) and fermentative (lactate dehydrogenase, LD) profiles. Graded cycle ergometer exercise to determine the intensities corresponding to onset of blood lactate accumulation set to 4.0 mmol x l-1 (WOBLA) and symptom limited exercise ('maximal', WSL) were also undertaken. Eleven (11) subjects had also recently participated in a marathon race. UQ was positively related to CS (r = 0.67, p < 0.001) and %ST (r = 0.60, p < 0.001) but not to LD. UQ was also positively related to exercise capacity and/or marathon performance (e.g. WOBLA x kg-1 BW, r = 0.70, p < 0.001). It was suggested that muscle UQ allocation in man was related to variables describing molecular oxygen availability, respiratory activity and oxidative energy releasing processes but not to fermentation activity. UQ allocation to ST fibers/CS activity was suggested to be due to the double role of UQ: 1) as a mitochondrial coenzyme (CoQ10) and 2) as a nonspecific antioxidant.
