Our aim was to assess the reproducibility and the reliability of the Weber classification system for fractures of the ankle based on anteroposterior and lateral radiographs. Five observers with varying clinical experience reviewed 50 sets of blinded radiographs. The same observers reviewed the same radiographs again after an interval of four weeks. Inter- and intra-observer agreement was assess...

Background: The Singh index is an inexpensive simple method to evaluate bone density, commonly used to assess osteoporosis is based on the radiological appearance of the trabecular bone structure of the proximal femur on a plain antero-posterior (AP) radiograph. The purpose of this study was to compare between Singh index and bone mineral density measurement using dual energy X-ray abs...

OBJECTIVE To investigate the inter- and intra-observer reliability of both qualitative and quantitative parameters used in the assessment of nail-fold capillaroscopy images. METHODS Fifty mosaic nail-fold images of healthy controls (n = 10), patients with primary RP (n = 10) and SSc (n = 30) were assessed in random order by two blinded observers on two occasions at centres in Sweden, UK and T...

BACKGROUND Orthopaedic surgeons disagree considerably when classifying fractures of the proximal humerus. However, the clinical implications of low observer agreement remain unclear. The purpose of the study was to compare the agreement on Neer classification with the agreement on treatment recommendations. METHODS We conducted a multi-centre observer-study. Five experienced shoulder surgeons...

OBJECTIVE The objective of this study was to compare inter- and intra-observer agreement using the Garnavos and AO/ASIF systems for classifying humeral diaphysis fractures . METHODS Eighty X-ray images taken of humeral diaphysis fractures in adult patients (age≥18 years) between January 2013 and September 2015 in the Radiology Department of Hospital São Paulo were selected for subsequent clas...

PURPOSE To evaluate the intra- and inter-observer reproducibility of the Gartland radiographic classification for supracondylar humeral fractures in children. METHODS Anteroposterior and lateral radiographs of 50 supracondylar humeral fractures in children were graded on 2 separate occasions by 4 orthopaedic surgeons according to the Wilkins modification of the Gartland classification. Data w...

Abstract Objective To evaluate the feasibility of systematic observer training in drug-induced sedation endoscopy (DISE) interpretation. Methods Fifty DISE videos were randomly selected from a group 200 cohort patients with OSA and/or snoring. The assessed blindly and independently using modified VOTE classification by an expert two novice observers starting their training. A approach was initi...
