Measurement of observer agreement.
Statistical measures are described that are used in diagnostic imaging for expressing observer agreement in regard to categorical data. The measures are used to characterize the reliability of imaging methods and the reproducibility of disease classifications and, occasionally with great care, as the surrogate for accuracy. The review concentrates on the chance-corrected indices, kappa and weig...
متن کاملOptic disc measurement with the Zeiss four mirror contact lens.
A knowledge of the optic disc size may be of value when assessing the glaucoma suspect. The vertical diameter of the optic disc was measured using a Zeiss four mirror gonioscope and a 900 Haag-Streit slit-lamp in one eye of 39 patients, 32 with refractive errors within 3 dioptres of emmetropia. The disc was measured by projecting a slit beam of known height onto the image of the disc. A magnifi...
متن کاملInter-Observer Agreement in Measuring Respiratory Rate
BACKGROUND Respiratory rate (RR) is an important vital sign which is strongly correlated with in-hospital mortality. At the same time, RR is the most likely vital sign to be omitted when assessing a patient. We believe that one reason for this could be the difficulty in measure the RR, since it is not read off a monitor, but counted manually. Also there is the possibility of assessment bias and...
متن کاملInter-observer agreement in myelodysplastic syndromes.
We read with great interest the recent paper by Senent et al. and the accompanying editorial on the reproducibility of WHO 2008 criteria and inter-observer agreement regarding the assessment of dysplasia for diagnosis and classification of myelodysplastic syndromes (MDS). The reproducibility of any composite criteria is mainly based on both the constituting components and the precise manner in ...
متن کاملCLINICAL SCIENCE Agreement in assessing optic discs with a digital stereoscopic optic disc camera (Discam) and Heidelberg retina tomograph
Aims: To assess the intraobserver agreement, interobserver agreement, and the agreement between a digital stereo optic disc camera (Discam) and Heidelberg retina tomograph (HRT) in measuring area cup-disc ratio (ACDR) and radial cup-disc ratio (RCDR) by two observers. Methods: The optic discs of 78 eyes of 39 people (17 cases of primary open angle glaucoma, eight normal tension glaucoma, two oc...
