Behavior of test specificity under an imperfect gold standard: findings from a simulation study and analysis of real-world oncology data [PDF]

BMC Medical Research Methodology
Background Gold standards used in validation of new tests may be imperfect, with sensitivity or specificity less than 100%. The impact of imperfection in a gold standard on measured test attributes has been demonstrated formally, but its relevance in ...
