BACKGROUND AND PURPOSE: Accurate and reliable detection of medium-vessel occlusions is important to establish the diagnosis of acute ischemic stroke and initiate appropriate treatment with intravenous thrombolysis or endovascular thrombectomy. However, medium-vessel occlusions are often challenging to detect, especially for unexperienced readers. We aimed to evaluate the accuracy and interrater agreement of the detection of medium-vessel occlusions using single-phase and multiphase CTA.

Interrater Agreement and Combining RatingsInterrater Agreement • November 29th, 2005
Some behaviors such as smiles require human raters for their measurement. A model of the rating process is explored that assumes that the probability distribution of overt rating responses depends on which of several underlying or latent responses occurred. The ideal of theoretically identical raters is considered and also departures from such identity. Methods for parameter estimation and assessing goodness of fit of the model are presented. A test of the hypothesis of identical raters is provided. Simulated data are used to explore different measures of agreement, optimal numbers of raters, how the ratings from multiple raters should be used to arrive at a final score for subsequent analysis, and the consequences of departures from the basic assumptions of identical raters and constant underlying response probabilities. The results indicate that often using two or three raters to rate all of the data, assessing the quality of their ratings by assessing their pairwise correlations, an
Interrater Agreement of the Quality Standards AssessmentInterrater Agreement • June 28th, 2021
In this study, we evaluated interrater agreement (IRA) of the Quality Standards Assessment (QSA). IRA is the absolute consensus in rating scores from multiple raters on the same targets. High IRA justifies aggregation of scores from multiple raters.
Interrater Agreement of Anal CytologyInterrater Agreement • June 6th, 2012
BACKGROUND: The majority of anal cancers are caused by persistent infections with carcinogenic human papillomavi- ruses (HPV). Similar to cervical carcinogenesis, the progression from HPV infection to anal cancer occurs through precan- cerous lesions that can be treated to prevent invasion. In analogy to cervical cytology, anal cytology has been proposed as a screening tool for anal cancer precursors in high-risk populations. METHODS: The authors analyzed the interobserver reproducibility of anal cytology in a population of 363 human immunodeficiency virus (HIV)-infected men who have sex with men (MSM). Liquid-based cytology (LBC) specimens were collected in the anal dysplasia clinic before the perform- ance of high-resolution anoscopy on all patients. Papanicolaou-stained LBC slides were evaluated by 2 cytopathologists, each of whom was blinded to the clinical outcome and the other pathologist’s results, using the revised Bethesda termi- nology. RESULTS: Overall agreement between the

Interrater agreement statistics under the two-rater dichotomous-response case with correlated decisionsInterrater Agreement • February 14th, 2024
Measurement of the interrater agreement (IRA) is critical in various disciplines. To correct for potential confounding chance agreement in IRA, Cohen’s κ and many other methods have been proposed. However, owing to the varied strategies and assumptions across these meth- ods, there is a lack of practical guidelines on how these methods should be preferred even for the common two-rater dichotomous rating. To fill the gaps in the literature, we system- atically review nine IRA methods and propose a generalized framework that can simulate the correlated decision processes behind the two raters to compare those reviewed meth- ods under comprehensive practical scenarios. Based on the new framework, an estimand of “true” chance-corrected IRA is defined by accounting for the “probabilistic certainty” and serves as the comparison benchmark. We carry out extensive simulations to evaluate the performance of the reviewed IRA measures, and an agglomerative hierarchical clustering analysis is condu
