RATIONALE AND OBJECTIVES The authors describe how to perform power and sample size computations for the Dorfman-Berbaum-Metz method for analyzing multireader receiver operating characteristic (ROC) studies when data from a pilot study or from a previous study similar to the planned study are available. MATERIALS AND METHODS Power and sample size computations are described in a step-by-step procedure. RESULTS To illustrate the power computation method we treat 2 studies that did not show a… CONTINUE READING
