- aOdds ratio for difference between patients with/without “OFF” episodes from ordered logistic regression on the categorical EQ-5D responses (indicating no problem/some problem/extreme problem). bEffect coefficient for difference between patients with/without “OFF” episodes from linear regression on EQ-5D utility index and VAS; − indicates a lower score on the EQ-5D utility index or VAS, indicating poorer health status, in patients with “OFF” episodes compared with patients without “OFF” episodes
