Changes in plasma concentration of cell-free DNA in response to physical activity.

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
Introduction: Plasma concentrations of cell-free DNA (cfDNA) serve as markers of overtraining or muscle injury. We examined whether nuclear (n) or mitochondrial (mt) cfDNA has potential as a marker of muscle burden or damage. Material and methods: Ten healthy, physically active volunteers (6 females, aged 27.1 ±6.8 years) performed a downhill running test. Samples for cfnDNA and cell-free mitochondrial DNA (cfmtDNA) analysis were collected before, 30 min, 1 h, and 14 days after the downhill run. CfnDNA and cfmtDNA (two markers for each) were analyzed using qPCR. Results: There was an extreme (~40-fold) increase in cfnDNA at the 30-min time-point against the baseline ( Conclusions: Our study confirmed the extreme release and clearance of cfnDNA in physically active subjects after strenuous exercise. In contrast, the trajectory of cfmtDNA concentrations seems to have much higher inter-individual variability than cfnDNA concentrations.
