title: Issues in clinical-analogue research versus issues in research compliance.
abstract: The study by Francis and Stanley is not about clinical-analogue differences but about differences between student-subjects recruited by a known investigator who potentially could influence their course grades versus an unknown investigator who lacks that ability. In such research, differences in mean scores and compliance rates must be investigated in comparable and unconfounded subject samples.
