Age-associated changes of exercise-induced plasma catecholamine responses.
Article in European journal of applied physiology and occupational physiology, 1986. 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
Age-associated plasma catecholamine responses were evaluated in 10 young (25 +/- 3 years) and 11 older competition cyclists (66.2 +/- 6 years) during incremental ergometric cycling. Noradrenaline levels were higher in the older subjects at rest, at identical work loads and at exhaustion. Adrenaline levels were similar in both groups at rest, higher in the old test subjects at identical work loads and lower in the old subjects at exhaustion. The noradrenaline-adrenaline ratio changed significantly depending on age from 5.1 +/- 0.5 to 8.7 +/- 2.1 which indicated higher adrenaline-related noradrenaline responses. The observed age-related differences may be caused by a compensatory mechanism which depends both on negatively age-correlated physical fitness, and on the decreased sensitivity of the organism to beta-adrenergic stimulation with age, as well as on an age-dependent change in the clearance of catecholamines from the circulation as described by Esler et al. (1981).
