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