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
Endurance training camps are well established in elite sports, but one-week camps for recreational endurance athletes have recently gained popularity despite limited scientific evidence. This study investigated the effects of a one-week endurance training camp on body composition, endurance performance, and markers of metabolic stress and mitochondrial adaptation in recreational athletes. Female and male endurance athletes (≥18 years) participated in a professionally guided one-week endurance training camp. Assessments included body composition, running diagnostics, sleep-quality/recovery-stress questionnaires, nutrition/energy balance diaries, blood profiling, and mitochondrial biogenesis markers. Measurements were conducted before (pre), during (camp), and after the camp (post). A total of 35 participants (18 male/17 female) were included. Body mass and body fat decreased from pre- to post-camp. Lactate concentrations at threshold levels changed, while velocities at fixed lactate concentrations and maximal oxygen uptake did not significantly improve. Post-camp, lactate dehydrogenase, klotho, and vitamin D increased, whereas interferon-γ, kynurenine, cortisol, creatinine, and ferritin decreased. Plasma mitochondrial and nuclear DNA abundance, as well as PGC1-α expression, increased, while vascular endothelial growth factor decreased. A one-week endurance training camp in a holiday-like setting induces measurable physiological, metabolic, and mitochondrial adaptations in recreational athletes and is associated with reduced systemic and psychological stress. However, the concurrent increase in muscle- and cell-stress markers indicates a substantial physiological load.
