Effects of acute exercise performed at different times of day on respiratory, blood pressure, and cardiac autonomic modulation outcomes in patients with obstructive sleep apnea: a randomized crossover trial.

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
This study aimed to analyze the effect of acute aerobic exercise at different times of the day on respiratory sleep parameters, blood pressure (BP), and cardiac autonomic modulation in patients with obstructive sleep apnea (OSA). In this randomized cross-over trial, 22 patients with OSA were recruited and completed four experimental sessions in random order: aerobic exercise and control in the morning (8:00-11:00 AM) and in the afternoon (3:30-6:30 PM). Each exercise session consisted of 40 min of aerobic exercise on a treadmill at 54-59% heart rate reserve; each control session consisted of seated rest for 40 min. Measurements were taken in the supine position before and after each session for clinic and central BP and cardiac autonomic modulation (by heart rate variability). After each session, all patients underwent at-home polysomnography using a portable polygraph. Clinic and central systolic BP decreased following both morning (Clinic: -16.1 mmHg; 95%CI = -22.5--9.7 mmHg; p < 0.001; Central: -13.3 mmHg -21.6--5.0 mmHg, p = 0.002) and afternoon (Clinic: -11.4 mmHg; 95%CI = -16.8--5.9 mmHg; p = 0.03; Central: -13.9 mmHg; 95%CI = -20.1--7.7 mmHg; p < 0.001) exercise sessions; however, no significant difference was observed between sessions. No significant changes were observed regarding diastolic BP, respiratory, or heart rate variability parameters (p > 0.05 for all). In conclusion, a single session of aerobic exercise has no effect on respiratory sleep parameters but led to a similar reduction in systolic blood pressure following both morning and afternoon sessions.
