Interval between Test and Retest Visits for HCP Retest Subjects
A subset of HCP twin pair Subjects were recruited for a full retest of the HCP 3T scan protocol and behavioral battery in a second retest visit. We made an effort to schedule the retest visit as soon as possible after the initial study visit, as the scanner schedule (booked scheduled approximately 6 months out for the life of the study) and travel arrangements allowed. As possible, we also tried to schedule retest visits for the twin pair to come back together.
The spreadsheet HCP_Test_Retest_Interval_Binned_Months_2017Mar31.csv lists the time interval in approximate month bins between the initial Study visit (Test) and Retest visit for all released HCP Retest subjects.
