Evaluating agreement in different diagnosis methods is necessary

J Med Virol. 2022 Sep 2. doi: 10.1002/jmv.28117. Online ahead of print.


Prazuck et al. evaluated an innovative two-step self-test, the AAZ COVID-VIRO ALL IN ®, switching from the classic nasal swab to a nasal sponge. We notice that the agreement between COVID-VIRO ALL IN ® and RT-PCR was not assessed. Although the authors had evaluated the overall agreement between COVID-VIRO ALL IN ® and RT-PCR, applying overall agreement to evaluate intra-rater consistency is not always appropriate. Our second concern is about the precise number of patients. Thinking the exact number of patients is a prerequisite for statistical analysis, we would be grateful if the authors could explain their data in detail and clarify the misunderstanding.
