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
Background: Among the key factors for cross-country skier training are high altitude training and strength in double-polling, because has recently been used not only for long-distance races but also for World cup. This study aimed to identify the effects of artificially induced high altitude on acute performance changes during aerobic (AE) and anaerobic (ANE) threshold exercises. Sport-specific tests simulating double-poling cross-country skiing were performed. Methods: Eleven (8 ♂ and 3 ♀) highly trained cross-country skiers (age 19±2.81, BMI 21.9±2.1) performed a stress test to determine individual AE and ANE levels and AE and ANE intensity tests at low (500 m ASL) and artificially induced high (2000 m ASL) altitudes. The altitude was simulated using the hypoxic generator HYP-100™. For double-poling, the ergometer SkiErg Results: For the AE and ANE loads, the average HR values at an artificially induced high altitude were 3-5% higher than those at a low altitude. The differences were significant, both statistically (p<0.05) and substantively. The average LC values were neither statistically significant (p>0.05) nor substantively significant. Conclusions: Not-adapted youth elite cross-country skiers have higher HR at artificially induced high altitudes (2000 m ASL) during the test on SkiErg
