OBJECTIVES Current studies on the additional benefit of using computed tomography (CT) in order to evaluate the surgeons' agreement on treatment plans for fracture are inconsistent. This inconsistency can be explained by a methodological phenomenon called 'spectrum bias', defined as the bias inherent when investigators choose a population lacking therapeutic uncertainty for evaluation. The aim ...

Results Intra-observer variability was assessed using intraclass correlation coefficient (ICC); inter-observer variability was assessed using Bland Altman plots for agreement. Intra-observer variability was low for both observers (ICC; observer 1 EDV: 0.99, ESV: 0.93, mass: 0.94 vs observer 2 EDV: 0.97, ESV: 0.97, mass: 0.94). Interobserver variability was lowest for volumes and highest for mas...

BACKGROUND The association between body composition (e.g. sarcopenia or visceral obesity) and treatment outcomes, such as survival, using single-slice computed tomography (CT)-based measurements has recently been studied in various patient groups. These studies have been conducted with different software programmes, each with their specific characteristics, of which the inter-observer, intra-ob...

BACKGROUND This study was conducted to assess intra-observer and inter-observer agreements for the measurement of dual-input whole tumor computed tomography perfusion (DCTP) in patients with lung cancer. METHODS A total of 88 patients who had undergone DCTP, which had proved a diagnosis of primary lung cancer, were divided into two groups: (i) nodules (diameter ≤3 cm) and masses (diameter >3 ...

OBJECTIVE To evaluate the inter- and intra-observer variability among radiologists in the characterisation of mammograms according to Breast Imaging Reporting and Data System assessment and breast density categories. METHODS The descriptive cross-sectional study was conducted at Aga Khan University Hospital, Karachi, from January 2014 to June 2014. Using non-probability purposive sampling, al...

INTRODUCTION Abdominal auscultation is a part of the clinical examination of patients, but the determining factors in bowel sound evaluation are poorly described. The aim of this study was to assess inter- and intra-observer agreement in physicians' evaluation of pitch, intensity and quantity in abdominal auscultation. MATERIAL AND METHODS A total of 100 physicians were presented with 20 bowe...

BACKGROUND Fractures of the proximal radius need to be classified in an appropriate and reproducible manner. The aim of this study was to assess the reliability of the three most widely used classification systems. METHODS Elbow radiographs images of patients with proximal radius fractures were classified according to Mason, Morrey, and Arbeitsgemeinschaft für osteosynthesefragen/Association ...

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...

The reproducibility of the AO classification for distal radius fractures remains a topic of debate. Previous studies showed variable reproducibility results. Important treatment decisions depend on correct classification, especially in comminuted, intra-articular fractures. Therefore, reliable reproducibility results need to be undisputedly determined. Hence, the study objective was to assess i...
