Intra‐observer and inter‐observer variation of Hertel exophthalmometry

Ophthalmic and Physiological Optics, 2009
AbstractPurpose:  This study investigated the intra‐observer and inter‐observer variation of Hertel exophthalmometry.Methods:  Seventy normal Chinese adults had bilateral exophthalmometry performed by two examiners. The two examiners were masked to the measurement results.

Inter-observer and intra-observer variation in bone histomorphometry

Calcified Tissue International, 1986
Inter-observer variation has been examined for a number of histomorphometric indices in 20 normal human iliac crest biopsies. Quantitation was performed using an eye-piece graticule and eye-piece micrometer. The same sections were examined by two observers and the methodology was identical. Intra-observer variation was also assessed.

Model-Free Predictive Current Control of PMSM Drives Based on Extended State Observer Using Ultralocal Model

IEEE transactions on industrial electronics (1982. Print), 2021
Conventional model predictive current control (MPCC) is a powerful control strategy for three-phase inverters that has the advantages of simple concept, quick response, easy implementation, and good performance.

Observer variation and depressive phenomenology

Psychological Medicine, 1977
SynopsisAn investigation into observer variation and depressive phenomenology is described. A group of 6 clinicians independently completed a 43-item sheet for 20 depressed patients at the same clinical interview. The coefficient of agreements on the items are given.

Observer Variation in Bronchographic Diagnosis

The British Journal of Radiology, 1958
Observer variation* in the interpretation of chest radiographs has been estimated by a number of workers (Birkelo, Chamberlain, Phelps, Schools, Zacks and Yerushalmy, 1947; Cochrane and Garland, 1952; Fletcher and Oldham, 1949; Garland, 1949; Springett, 1956; Stradling and Johnston, 1953; Yerushalmy, Harkness, Cope and Kennedy, 1950; Yerushalmy ...

Observer Variation in Abdominal CT

Investigative Radiology, 1984
Observer performance in radiologic interpretation has traditionally been based upon Receiver Operating Characteristic (ROC) analysis. A statistical method that evaluates the reproducibility or consistency of radiologic interpretation is presented. Since this method is not based upon pathologic verification, it cannot be used to assess accuracy of ...

Observer variation in skeletal radiology

Skeletal Radiology, 1983
The factors that affect observer variation in bone radiology are analysed from data in the literature and on the basis of studies carried out at McMaster University on the hands and sacroiliac joints. A plea is made for presenting results in terms of Kappa statistics so that agreement due purely to chance is eliminated.

Observer variation in assessing renal scarring

The British Journal of Radiology, 1980
To examine the extent of variation between experienced observers in recognizing renal scarring, 60 intravenous urograms from schoolgirls with bacteriuria were presented separately to three radiologists with a major interest in the radiology of the urinary tract.

Observer variation in equine abdominal auscultation

Equine Veterinary Journal, 1990
Summary The reliability of abdominal auscultation was investigated via an observer variation study. Clinicians listened to a variety of minute‐long equine gut sound recordings. They evaluated the amount of gut sounds as ‘absent’, ‘decreased’, ‘normal’, or ‘increased’.
