  • Description: <jats:title>Abstract</jats:title><jats:p>The coefficient of variation (CV) is often used in proteomics as a proxy to characterize the performance of a quantitation method and/or the related software. In this note, we question the excessive reliance on this metric in quantitative proteomics that may result in erroneous conclusions. We support this note using a ground‐truth Human‐Yeast‐<jats:italic>E. coli</jats:italic> dataset demonstrating in a number of cases that erroneous data processing methods may lead to a low CV which has nothing to do with these methods’ performances in quantitation.</jats:p>
