“…Kappa values range from -1 to +1; values between -1 and 0 indicate that the observed agreement was lower than what was randomly expected, 0 indicates the random agreement level, and +1 indicates total agreement. 17 In general, kappa values of less than 0. 5 and another four presented x-rays produced with the forearm immobilized in plaster.…”

“…Data were collected on spreadsheets and the kappa (κ) coefficient was used to assess agreements. k was applied using the method proposed by Fleiss et al 17 , and the random expected agreement calculation described by Scott 18 and Cohen 19 was also used. The latter two methods enable calculation of agreements for multiple (more than two) observers with regard to evaluations of nominal variances.…”

Are distal radius fracture classifications reproducible? Intra and interobserver agreement

et al. 2008

CONTEXT AND OBJECTIVE: Various classifi cation systems have been proposed for fractures of the distal radius, but the reliability of these classifications is seldom addressed. For a fracture classification to be useful, it must provide prognostic signifi cance, interobserver reliability and intraobserver reproducibility. The aim here was to evaluate the intraobserver and interobserver agreement of distal radius fracture classifi cations. DESIGN AND SETTING:This was a validation study on interobserver and intraobserver reliability. It was developed in the Department of Orthopedics and Traumatology, Universidade Federal de São Paulo -Escola Paulista de Medicina.METHOD: X-rays from 98 cases of displaced distal radius fracture were evaluated by fi ve observers: one third-year orthopedic resident (R3), one sixth-year undergraduate medical student (UG6), one radiologist physician (XRP), one orthopedic trauma specialist (OT) and one orthopedic hand surgery specialist (OHS). The radiographs were classifi ed on three different occasions (times T1, T2 and T3) using the Universal (Cooney), Arbeitsgemeinschaft für Osteosynthesefragen/ Association for the Study of Internal Fixation (AO/ASIF), Frykman and Fernández classifi cations. The kappa coeffi cient (κ) was applied to assess the degree of agreement. RESULTS:Among the three occasions, the highest mean intraobserver k was observed in the Universal classifi cation (0.61), followed by Fernández (0.59), Frykman (0.55) and AO/ASIF (0.49). The interobserver agreement was unsatisfactory in all classifi cations. The Fernández classifi cation showed the best agreement (0.44) and the worst was the Frykman classifi cation (0.26). CONCLUSION:The low agreement levels observed in this study suggest that there is still no classifi cation method with high reproducibility.

“…Previous studies 3,6,7,24 have focused on the interexaminer agreement for evaluation of caries, signs and symptoms of periodontal disease and radiographic examinations. All these studies have employed relatively objective data, such as pocket probing depth, bone loss and presence or absence of caries, whereas standardization of CR manipulation is based on less objective data.…”

Centric relation (CR) has been considered a maxillomandibular position of choice for some dental and prosthetic procedures. Although regarded as a fully reproducible relation, there is great controversy about its clinical use and recording technique, especially in patients with signs and symptoms of temporomandibular disorders (TMD). This study aimed at evaluating the effectiveness of a training program on intra-and interexaminer agreement when determining the clinical record of the CR position. Forty individuals constituted the sample, divided into symptomatic (TMD) and asymptomatic groups. Three previously calibrated examiners performed the initial assessment and the second evaluation after 30 days in a blind design, using Dawson's bilateral manipulation technique with and without an anterior stop. The amount of frontal and sagittal deviations in relation to intercuspal position, the presence of pain and discomfort during manipulation, and the first occlusal contact in CR were analyzed. Kendall and Kappa tests with a 5% level of significance were used to determine agreement. Values for both intra-and interexaminer agreement were deemed good. The best results were obtained for frontal deviations and assessment of pain (or absence of it) during manipulation. Sagittal deviations showed the lowest agreement in both examinations. The authors concluded that a calibration program could be effective for intra-and interexaminer agreement when recording centric relation. However, caution is recommended when analyzing some isolated items. DESCRIPTORS: Centric relation; Temporomandibular joint disorders.RESUMO: Na tentativa de estabelecer uma posição maxilomandibular reprodutível em pacientes sem dentes suportes posteriores ou portadores de oclusão instável, o conceito de relação cêntrica (RC) foi introduzido. Apesar de ser utilizada como uma posição de referência, existe uma considerável divergência de opiniões sobre a sua reprodutibilidade. Este estudo procurou avaliar se os métodos de treinamento profissional são efetivos na análise e obtenção de RC. Para isso utilizou-se uma amostra de 40 indivíduos, divididos em 20 assintomáticos e 20 portadores de disfunções da ATM. Os indivíduos foram avaliados por 3 examinadores, previamente calibrados. Foram realizados 2 exames: inicial e final (30 dias após o inicial), possibilitando dessa forma, análise da concordância interexaminadores, assim como intraexaminadores. Posteriormente, os resultados foram submetidos à análise estatística, utilizando-se os testes de concordância de Kendall e de Kappa. Os resultados foram considerados bons, sendo os melhores obtidos para a análise do desvio frontal e relato de dor (ou ausência) durante a manipulação. Os autores concluíram que os programas de calibração podem ser efetivos para análise da RC. No entanto, cautela é recomendada quando da análise de alguns itens isolados.

“…The kappa values can range from -1 to +1; values between -1 and 0 indicate that the concordance observed was less than what would be expected by chance; 0 indicates a concordance level that would be expected by chance; and +1 indicates total concordance. In general, kappa values lower than 0.5 are considered to be unsatisfactory; values between 0.5 and 0.75 are considered to be satisfactory and adequate; and values greater than 0.75 are considered to be excellent (25)(26)(27) . The parameters for normality, which were used in conformity with the literature, are described in Table 1.…”

Objective: To analyze the most common methods for measuring patellar height and the impact of observer experience in correlations with the other observers using digital radiography. Methods: Sixty digital radiographs of the knee in lateral view were analyzed by four observers: a physician in the second year of medical residence in orthopedics (R2); a physician in the third year of medical residence in orthopedics (R3); an orthopedic surgeon who was a specialist in knee surgery (SK); and a radiologist who was a specialist in musculoskeletal radiology (SR). The indices used were: Insall-Salvati (IS), Blackburne--Peel (BP), Caton-Deschamps (CD) and modified Insall-Salvati
