The aim of the present study was to determine the reproducibility of measurement of resting metabolic rate (RMR) using a ventilated-hood indirect calorimeter in children using a short protocol suitable for the outpatient setting or home visit. The protocol consisted of an overnight (10-12 h) fast, 5-10 min supine rest, 5-10 min 'settling in' under the ventilated hood, and 12-16 min of measureme...

PURPOSE To evaluate intraobserver and interobserver reproducibility of measurement of images obtained during ultrasound biomicroscopy. METHODS Four anterior segment images of four normal patients were obtained by a single examiner. The measurements of three independent observers were compared to assess interobserver reproducibility in quantifying the images. Thirteen different anterior segmen...

OBJECTIVE Indicators of reproducibility for log-transformed variables can often not be calculated straightforwardly and are subsequently incorrectly interpreted. METHODS AND RESULTS We discuss meaningful Coefficients of Variation (CV) for log-transformed variables, which can be derived directly from the standard error of the log-transformed measurements. To provide easy interpretable Bland an...

I have read with interest the paper by SENÉTERRE et al. [1]. However, perhaps the method used to assess the reproducibility of the measurements is not the best one. The authors use Spearman's rank test, and they find an "excellent and highly significant" reproducibility, since r-value is 0.99 in all cases. Considering that correlation is different from agreement, BLAND and ALTMAN [2] have propo...

OBJECTIVES To compare the acceptability, reproducibility, and sensitivity of spirometric outcome measures of airway caliber during challenge testing in children. DESIGN FEV(1), forced expiratory volume in 0.75 s, forced expiratory volume in 0.5 s, and peak expiratory flow (PEF) were recorded during stepwise dosimetric histamine challenge tests. The responses were compared, and the reproducibi...

background: we have validated the monitor unit calculations from a commercially available treatment planning system (tps) for three intensity modulated radiotherapy (imrt) planning techniques for tangential breast irradiation by using ionization chamber measurements. materials and methods: treatment plans were generated for forty-two breast patients by a forward planned field in field technique...

OBJECTIVES Left atrial appendage (LAA) dilatation and morphology may influence an individual's risk for intracardiac thrombi and ischemic stroke. LAA size and morphology can be evaluated using cardiac computed tomography (cCT). The present study evaluated the reproducibility of LAA volume and morphology assessments. METHODS A total of 149 patients (47 females; mean age 60.9±10.6 years) with s...
