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
backgroundThis study aimed to investigate the recovery effects and timing sequence of Mild Hyperbaric Oxygen Therapy (MHOT) on physiological responses and exercise capacity following muscle fatigue induced by simulated cycling exercise.
methodsThis study employed a controlled crossover design. Twelve Chinese secondary national-level male athletes participated in two identical trials (CON and MHOT). Each trial consisted of one daily session for six consecutive days. In each session, participants first completed 90 min of cycling exercise to induce fatigue. Afterward, six participants underwent the CON intervention, while the other six received MHOT; the interventions were switched in the alternate trial. Physiological outcomes included the Pittsburgh Sleep Quality Index (PSQI), aerobic exercise exhaustion test (maximal oxygen uptake (V̇O₂max), maximal cycling power, maximal cycling time), Wingate anaerobic test, and brain and muscle tissue oxygenation indices. Measurements were taken at six time points across the study.
resultsAfter six interventions, the MHOT group showed significantly better subjective sleep quality compared with CON (p < 0.05). MHOT also increased muscle and brain oxygenated hemoglobin as well as muscle total hemoglobin (p < 0.05). At 24 h after the sixth intervention, the MHOT group demonstrated higher V̇O₂max, maximal cycling power, and cycling time compared with CON (p < 0.05). However, no significant differences were observed between MHOT and CON in Wingate test indices (p > 0.05).
conclusionsRepeated MHOT sessions promoted recovery by improving subjective sleep quality, enhancing brain and muscle oxygenation, and augmenting aerobic exercise performance compared with CON. However, MHOT did not significantly influence anaerobic capacity as assessed by the Wingate test.
