Values are presented as mean ± SEM, median (range) summing costs and health care utilization per patient during the five years prior to OSA diagnosis. Comparison between OSA patients and matched controls was performed by Wilcoxon test. Comparison between women and men OSA patients performed by Mann-Whitney test (* P < 0.05, # P < 0.0001).
