• Patients with comorbid insomnia reported more severe psychiatric symptoms, including depression and anxiety.
• Male patients with comorbid insomnia had lower sleep efficiency (p = 0.02) compared to those with obstructive sleep apnea alone.
• Longer sleep latency was observed in the male comorbid insomnia group (p = 0.002).
• A higher apnea-hypopnea index was found in the male comorbid insomnia group (p = 0.04).
• The male comorbid insomnia group exhibited a lower mean oxygen saturation (p = 0.004) than the OSA-only group.
