- Follow Up
- Out of the 5062 enrolled, and of those due for follow-up (i.e. at least 18 months has passed since their last visit), longitudinal data have been collected as follows: 3187 (3187/4149 = 76.8%) have had two or more visits; 1691 (1691/2299 = 73.6%) have had three or more visits; and 628 (628/889 = 70.6%) have had four or more visits. Thus, our retention rate is more than 70%. Attrition in this follow-up rate is due to study withdrawal (reasons given include lack of time and lack of interest) and loss to follow-up as a result of an unknown address or the family having changed physicians or moved away
