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
backgroundCoenzyme Q10 (CoQ10), a vital mitochondrial antioxidant, may enhance cardiovascular recovery and delay fatigue in athletes. This double-blind, randomized, placebo-controlled trial investigated CoQ10's effects on cardiac stress markers and exercise performance in 16 professional soccer players.
methodsParticipants received either CoQ10 (n = 8) or placebo (n = 8) for 30 days and completed exhaustive aerobic cycling tests pre- and post-supplementation. Blood samples were collected at six time points to analyze GDF-15, NT-proBNP, and hs-TnT levels.
resultsIn the CoQ10 group, GDF-15 rose post-exercise (PreEx1-PostEx1: +8.84%, p = 0.003; PreEx2-PostEx2: +5.37%, p = 0.001) but declined by 24 h post-Ex1 (- 5.28%, p = 0.003) and 24 h post-Ex2 (-6.62%, p = 0.001) compared to post-Ex1 & post-Ex2, respectively. NT-proBNP increased post-Ex1 (19.66%, p = 0.001), post-Ex2 (12.09%, p = 0.001) but decreased in 24 h-Ex1 (- 20.28%, p = 0.001), 24 h-Ex2 (-20.83%, p = 0.001) compared to post-Ex1&Ex2, respectively. Following a 31.18% increase post-Ex1, a smaller 23.65% increase was observed post-Ex2 in hs-TnT levels, however, decreases of -19.57 and - 32.20% were observed 24 h- postEx1&Ex2 compared to post-Ex1&Ex2, (p = 0.001 for all). Time to fatigue (TTF) improved post-supplementation (- 0.5%, p = 0.002), whereas the placebo showed no change (- 0.08%, p = 0.793).
conclusionsCoQ10 supplementation significantly reduced post-exercise cardiac stress markers (GDF-15, NT-proBNP, hs-TnT) and improved TTF in athletes. These findings suggest potential associations with reduced cardiac stress responses to exercise, but further studies are required to confirm the clinical significance and long-term effects of CoQ10 supplementation on cardiovascular health in athletes.
