It should be noted that this study did not employ an
intent-to-treat analysis because the study was concerned
with treatment efficacy and not with adherence to the
treatment. Therefore, the results focus only on those who
completed the trial. It was found, however, that those
who did not turn up for the first appointment and who
dropped out before completing phase 1 had significantly
higher scores on Conners Index as completed by parents
upon registration for the study than those who completed
phase 1 or the whole study.
