To the Editor: We read the concerns of Mr Sabour (1) with some interest. In our study (2), we essentially analyzed the agreement of body-scanner measurements between three repetitive assessments by the same observer (intra-observer reliability) and between body-scanner measurements and corresponding measurements of classical anthropometry if available (validity).

All analyzed measurements are quantitative. Except intra/interclass correlation coefficients, all statistical measures proposed by Sabour are designed for binary/categorical variables and cannot be applied in our situation. Moreover, proposed measures like sensitivity, specificity, etc, have nothing to do with agreement.
