background: los angeles classification is widely adopted as a means of unifying endoscopic observation for gerd. we assessed the inter- and intra-observer variability of la classification. materials and methods: two-hundred fifty-four still images of the lower esophagus taken by an expert endoscopist (rm) were randomly selected and presented to 9 gastroenterologists (2 females, 6 experts, 3 tra...

results inter-observer agreement of the pathology scores based on nas scoring system was acceptable for steatosis, lobular inflammation, and fibrosis, but not for hepatocyte ballooning. the intra-observer agreement was acceptable in all scales, with lowest intra-class correlation observed for lobular inflammation. materials and methods the anonymous liver biopsy samples of 100 consecutive nafld...

background: this study was aimed to compare the diagnostic accuracy and feasibility of cone beam computed tomography (cbct) with phosphor storage plate (psp) in detection of simulated occlusal secondary caries. materials and methods: in this in vitro descriptive-comparative study, a total of 80 slots of class i cavities were prepared on 80 extracted human premolars. then, 40 teeth were randomly...

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...

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...

The apparent diffuse coefficient (ADC) may correlate with the treatment response to chemotherapy/radiotherapy in solid tumors. Our aim was to determine the inter- and intra-observer reproducibility of ADC measurements in primary esophageal squamous cell carcinoma (ESCC). ADCs were blindly measured in 31 patients diagnosed with ESCC by two observers before treatment (pre-ADC) and after 5th fract...

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...

BACKGROUND The aim of this study was to determine the intra- and inter-observer variability in the evaluation of embryo quality. Multilevel images of embryos on day 1, day 2 and day 3, were analysed using different morphological parameters. METHODS Multilevel images of embryos on day 1, day 2 and day 3, were analysed using a standard scoring system. The kappa coefficient was calculated to mea...

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...

OBJECTIVE To assess inter- and intra-observer agreement in the detection of lymphadenopathy on chest radiography in children at risk for tuberculosis. PATIENTS AND METHODS Retrospective examination of the antero-posterior and lateral chest radiographs of children aged 1 month to 11 years discharged from the short-stay ward of the Red Cross Children's Hospital, Cape Town, with a diagnosis of t...
