Nobelitis: a common disease among Nobel laureates?

abstract：BACKGROUND:Highly-sensitive cardiac troponin (cTn) assays are being introduced into the market. In this study we argue that the classification of cTn assays into sensitive and highly-sensitive is flawed and recommend a more appropriate way to characterize analytical sensitivity of cTn assays. STUDY:The raw data of 225...
