A I. Responders to the first questionnaire a n = 509
B II. Responders to the reminder questionnaire a n = 156
C III. Responders after telephone follow-up n = 27
DAll Responders (original + reminder questionnaire + telephone) n = 656
E Difference in medians (I vs. II) (95% CI)
F P-value of difference (I vs. II)
G Difference in medians (I + II vs. IIl) (95% CI)
H P-value of difference (I + II vs. IIl)
a Incomplete responses to the original questionnaire are part of group I, and if the patients responded to the postal reminder, their second answer is part of group II.
