摘要: This chapter outlines the principles of designing, performing and interpreting high quality studies diagnostic test accuracy. The basic concepts accuracy, including sensitivity, spec-ificity, odds ratio (DOR), likelihood ratios (LRs) predictive values, are explained. Sources bias in accuracy explained with practical examples. graphical ways to represent a demonstrated. Issues consider when published study outlined using guidelines advocated medical literature. Finally, meta-analysis, bivariate hierarchical summary receiver operating characteristic methods,
