Comparison of fully automated computer analysis in nuclear SPECT

This study found that the Cedars-Sinai Total Perfusion Defect score performed well in comparison to two human readers. COMMENT:  this study compared two groups: computer vs human. The problem is that the "human" group consisted of only two readers. It would be a major misconception to assume that two expert readers adequately represent the entire population of expert readers in nuclear medicine. This is a common statistical error that was sadly repeated in this study.
