a For all rows in this section, do not include youth from clusters that dropped (attrited) over the course of the study. For example, if you randomly assigned 10 clusters (5 to each condition), and one intervention group cluster (e.g. school) dropped from the study, you would only include youth in this section from the 9 clusters that did not drop from the study. Because the cluster-level response rate in the above rows already captures that dropped cluster, you do not need to count youth from the lost clusters in your youth-level response rates.
b If consent occurred before assignment, delete this row. Add a note at the bottom of the table indicating that consent occurred before random assignment.
c See guidance in section III.E for defining your analytic sample(s).
