Reliability of Measurements for Studies of Cerebrov Vascular Atherosclerosis

The development of the methodology for assessing reliability of data is presented and within and between coder variability is estimated.

Abstract

For epidemiologic and comparative pathologic studies of cerebral atherosclerosis, assessment of reliability of measurements is necessary. Such a study is described along with the measurement method used. The development of the methodology for assessing reliability of data is presented. Within and between coder variability is estimated. For the biometrician, the salient feature is that several methods of determining reliability might have to be explored and tried before arriving at a method which is useful and acceptable to the clinician or clinical pathologist.
