Despite the fundamental importance of measurement in medicine, studies
which compare methods of clinical measurement are often analysed
inappropriately and may thus come to incorrect conclusions. We explain the
problems with the main methods used, notably correlation and regression,
and describe the limits of agreement approach which we have proposed. We
consider why incorrect methods are so widely used and describe our own
experience in bringing this issue to the attention of medical researchers.
