METHODS Sixty unselected cases with illustrated diagnostic criteria were circulated to 19 practising histopathologists. RESULTS Overall agreement was moderate for cytological grade in three categories: 71% agreement; w...
Investigators cite observer variability as a problem in using crackles to diagnose asbestosis. We measured agreement on the presence or absence of crackles noted during auscultation of 64 asbestos-exposed workers in order to clarify this question. There was 89 percent agreement between two observers who simultaneously examined subjects breathing from functional residual capacity (FRC). Kappa (k...
OBJECTIVES To estimate intraobserver repeatability and interobserver agreement in assessing the presence of papillary projections in adnexal masses and in classifying adnexal masses using the International Ovarian Tumor Analysis terminology for ultrasound examiners with different levels of experience. We also aimed to identify ultrasound findings that cause confusion and might be interpreted di...

Background The Decayed, Missing, Filled (DMF) index is one of the most common techniques for investigating dental decay. In recent years, the new International Caries Detection and Assessment System (ICDAS) technique has been introduced to the world as a standard tool to confront the present challenges in diagnosing dental decay. The present study aimed to investigate the reliability and repr...
BACKGROUND Kappa is commonly used when assessing the agreement of conditions with reference standard, but has been criticized for being highly dependent on the prevalence. To overcome this limitation, a prevalence-adjusted and bias-adjusted kappa (PABAK) has been developed. The purpose of this study is to demonstrate the performance of Kappa and PABAK, and assess the agreement between hospital ...
Background and Objectives: Making an accurate clinical diagnosis can be a great challenge with pediatricians. We aimed to compare the initial diagnosis and final diagnosis for hospitalized children in one teaching hospital in Iran.Methods: In this cross-sectional study, patients’ clinical files were used.
