cancer is the second most common cancer in Ko-rea, but mortality due to gastric cancer is decreasing. This phenomenon is probably a result of the National Cancer Screening Program, which provides biennial endoscopic screening and facilitates early detection of gastric cancer that can be cured by endoscopic treatment or minimally invasive surgery. 1 During the endoscopic screening, precancerous ...

Objective To measure the reliability of Albertoni's classification for mallet finger. Methods Agreement study. Forty-three radiographs of patients with mallet finger were assessed by 19 responders (12 hand surgeons and seven residents). Injuries were classified by Albertoni's classification. For agreement comparison, lesions were grouped as: (A) tendon avulsion; (B) avulsion fracture; (C) fra...

Existing indices of observer agreement for continuous data, such as the intraclass correlation coefficient or the concordance correlation coefficient, measure the total observer-related variability, which includes the variabilities between and within observers. This work introduces a new index that measures the interobserver variability, which is defined in terms of the distances among the ‘tru...

Three experienced physician readers assessed the chest radiographs of 743 men from a coal mining community in West Virginia for the signs of simple pneumoconiosis, using the ILO U/C 1971 Classification of Radiographs of the Pneumoconioses. The number of films categorised by each reader as showing evidence of simple pneumoconiosis varied from 63 (8.5%) to 114 (15.3%) of the 743 films classified....

Observation of the tongue, also known as tongue diagnosis, is an important procedure in diagnosis by inspection in Traditional Korean medicine (TKM). We investigated the reliability of TKM tongue diagnosis in stroke patients by evaluating interobserver reliability regarding tongue indicators as part of the project named the Fundamental Study for the Standardization and Objectification of Patter...

REASONS FOR PERFORMING STUDY The extent to which variability affects endoscopic grading of arytenoid cartilage movement is uncertain. OBJECTIVE To determine the observer and within horse variability of grading arytenoid cartilage movement in horses during resting endoscopic examination, using a 7-grade system. METHODS Endoscopic recordings of the upper respiratory tract made at rest in 270 ...

OBJECTIVE Most chest radiography scoring systems for patients with cystic fibrosis have been developed for children but are also used for adults. Our aim was to evaluate the intra- and interobserver variability of 2 radiographic scoring systems in adults with cystic fibrosis and to assess the correlation of these systems with clinical and spirometric parameters. PATIENTS AND METHODS The chest...

BACKGROUND AND PURPOSE Diffusion tensor imaging (DTI) has become a valuable tool in both the research and clinical evaluation of subjects. We sought to quantify interobserver and intraobserver variability of diffusivity and diffusion anisotropy measurements with regard to specific regions of interest (ROIs). MATERIALS AND METHODS The subject group consisted of 5 healthy control subjects and 7...

PURPOSE Chronic hand and wrist pain is a common clinical issue for orthopaedic surgeons and rheumatologists. The purpose of this study was 1. To analyze the interobserver agreement of SPECT/CT, MRI, CT, bone scan and plain radiographs in patients with non-specific pain of the hand and wrist, and 2. to assess the diagnostic accuracy of these imaging methods in this selected patient population. ...

UNLABELLED Sleep-disordered breathing (SDB) is often related to malocclusion, and dentists should be able to recognize occlusal changes that may be associated with the development, onset, or persistence of SDB. Although clinical examination is routinely used by specialists in orthodontics and functional jaw orthopedics, differences in diagnosis are very common. METHOD Two observers, both dent...
