| Men in MrOS | 82.0 (±4.0) | 15.4 (±5.9) | 4.5 (±6.9) | 1.2 (±4.9) | 51.3 (±18.9) | 17.3 (±21.6) | 37.8 (±21.5) | 369.0 (±83.8) | 58.4 (±14.0) | 13.9 (±14.3) |

Comparison between men in Osteoporotic Fractures in Men (MrOS) Study and women in the Study of Osteoporotic Fractures (SOF) using a subsample with identical age distribution. OAHI, obstructive apnea–hypopnea index; AI-NREM, arousal index; PLMSI, periodic limb movement in sleep index. *Significance level: p < 0.05.
