Changes of SaO 2 nadir, SaO 2 mean, and tcCO 2 median during sleep with MPA and after a 3- and a 6-week follow-up. Changes are absolute percentage values. MPA = medroxyprogesterone acetate, SaO2 = arterial oxygen saturation, tcCO2 = transcutaneous partial carbon dioxide tension. The error bars of SaO2 mean and tcCO2 median represent standard deviation and those of SaO2 nadir represent interquartile ranges. P-values are corrected with Bonferroni method. ** = p < 0.01, * = p < 0.05.
