یک روش جدید برای تصحیح سوگرایی تاییدی در مطالعات بررسی صحت تستهای تشخیصی با استفاده از رویکرد بیزین
Background & Objectives: One of the problems of diagnostic accuracy studies is verification bias. It occurs when standard test performed only for non-representative subsample of study subjects that diagnostic test done for them. In this study we extend a Bayesian method to correct this bias. Methods: Patients that have had at least twice repeated failures in cycles IVF ICSI were included i...
