(4) Returning sample cases without email addresses will not receive any contacts at weeks 16 and 20.
(5) Questionnaire Impact Experiment treatment groups could receive web invites rather than paper questionnaires at weeks 7 and 18.
(6) Email Reminder Experiment treatment groups could receive reminder emails at weeks 5 and 24 and reminder letters at weeks 16 and 20.
