Observer variation in the assessment of resin composite
Dental Materials, 1998The aim of this study was to compare the type of information obtained from log-linear modelling vs Cohen's kappa statistics on observer variation in the assessment of marginal adaptation in composite inlays and amalgam restorations.Marginal adaptation of Class II resin composite inlays and amalgam restorations was clinically assessed by two observers ...

Variation of Stereoscopic Acuity with Observation Distance
Journal of the Optical Society of America, 1963The stereoscopic acuity of five subjects was investigated in two consecutive and related studies. In the first one a modified horopter apparatus was used and the stereoscopic acuity was determined, at a mean retinal locus of 4° to the left of the fovea, at the 333- and 1000-mm observation distances.

Observer and experimental variation in tuberculin testing
Tubercle, 1970Abstract Investigations into the experimental and observer variations of the Mantoux and the multiple puncture (Heaf) tests are described. They were carried out on patients in a mental hospital and on students in four high schools in Western Australia. Tests were performed by one operator and the reactions read by up to three observers on from one to

Laser Resurfacing: Observations and Variations
International Journal of Cosmetic Surgery and Aesthetic Dermatology, 2000Laser resurfacing has become increasingly popular among cosmetic surgeons and the public during the last decade. Numerous brands and types of lasers are available. Countless choices of postsurgical wound care methods and mechanisms are available. New technology and variable practice patterns have resulted in less standardized care.

Observed phenotypic variation in a Paleozoic bryozoan
Paleobiology, 1995Documentation of morphologic variation within and among fossil species (and larger clades) provides fundamental data needed for studies of evolution, paleoecology, and the systematic foundation required for most fields of paleobiology. In paleontological (and, frequently, biological) studies, morphologic variation is used as a general proxy for genetic

Observer variation in the interpretation of xeromammograms.
Journal of the National Cancer Institute, 1982We have examined variation in the interpretation of xeromammograms among radiologists designated to take part in a Canadian multicenter randomized controlled trial of screening for breast cancer. Radiologists read 100 xeromammograms comprising 10 histologically proved cancers, 40 benign abnormalities, and 50 normal films.
