Increase of pro-oxidants with no evidence of lipid peroxidation in exhaled breath condensate after a 10-km race in non-athletes.
Article in Journal of physiology and biochemistry, 2014. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 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
It is a well-established fact that exercise increases pro-oxidants and favors oxidative stress; however, this phenomenon has been poorly studied in human lungs. Pro-oxidative generation (H(2)O(2), NO(2) (-)), lipid peroxidation markers (MDA), and inflammation (pH) in exhaled breath condensate (EBC) have been determined through data from 10 active subjects who ran 10 km; samples were obtained immediately before, at 20, and at 80 min post-exertion. In EBC, the concentration of H(2)O(2) at 80 min post-exertion was increased. NO(2) (-) concentration showed a tendency to increase at 80 min post-exertion, with no variations in MDA and pH. No variations of NO(2) (-) were found in plasma, while there was an increase of NO(2) (-) at 80 min post-exertion in the relation between EBC and plasma. NO(2) (-) in EBC did not correlate to plasmatic NO(2) (-), while it did correlate directly with H(2)O(2) in EBC, suggesting a localized origin for the exercise-related NO(2) (-) increase in EBC. MDA in plasma did not increase nor correlate with MDA in EBC. In conclusion, high-intensity exercise increases lung-originated pro-oxidants in non-athlete subjects with no evidence of early lipid peroxidation and changes in the pH value in EBC.
