Table 3 Multiple regression of the effect of age, sex and new pathology on change in (a) mental component summary (MCS) from baseline to 10-year follow-up, controlling for baseline MCS (R2 = 0.30), (b) physical component summary (PCS) from baseline to 10-year follow-up, controlling for baseline PCS (R2 = 0.30)

From: Health-related quality of life in Marfan syndrome: a 10-year follow-up
