No effect of exercise on urinary 6-sulfatoxymelatonin and catecholamines in young women participating in a 16-week randomized controlled trial.
Trial report in Cancer epidemiology, biomarkers & prevention : a publication of the American Association for Cancer Research, cosponsored by the American Society of Preventive Oncology, 2013. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers, 1 of them a synthesis that pooled it.
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
backgroundWomen with breast cancer have decreased levels of melatonin or its metabolite in plasma and/or urine.
methodsWe measured serum melatonin, urinary 6-sulfatoxymelatonin, catecholamines, and cortisol in 141 sedentary young female participants in a clinical trial comparing 150 min/wk aerobic exercise for 4 months to no-exercise controls. Demographics, health surveys, body composition, sleep quality, fitness levels, and blood and urine samples were obtained at baseline and 16 weeks.
resultsThere were no differences between groups at baseline in demographics, exercise, sleep habits, or study hormones. There were also no significant differences between groups in any of the hormones at 16 weeks.
conclusionSixteen weeks of exercise had minimal effects on melatonin secretion of young women. IMPACT: There is convincing evidence that exercise protects against breast cancer, but this does not appear to occur through changes in melatonin secretion.
