ADJUSTED ODDS RATIOS^* OF INCIDENT HYPERTENSION AT FOLLOW-UP IN RELATION TO BASELINE APNEA-HYPOPNEA INDEX AMONG 2,470 SLEEP HEART HEALTH STUDY SUBJECTS WITHOUT HYPERTENSION AT BASELINE

Baseline AHI	n	Model 1†	Model 2‡	Model 3§
0–4.9	1,511	—	—	—
5–14.9	629	1.13 (0.90–1.43)	0.92 (0.72–1.17)	0.94 (0.73–1.22)

Definition of abbreviations: AHI = apnea-hypopnea index; BMI = body mass index.

^*Estimated by generalized estimating equation models with each subject contributing one or two follow-up intervals.

Values are odds ratio (95% confidence interval) or n.

^†Adjusted for age, sex, race, and time since baseline.

^‡Adjusted for factors in model 1 plus BMI.

^§Adjusted for factors in model 2 plus waist/hip ratio and neck girth.
