The OS assessed adherence to statins 298 patients with high very cardiovascular risk for 3 months. oral anticoagulants 201 non-valvular atrial fibrillation 1 year. Adherence was using AS questionnaire, which external performed (with calcu...
We discuss properties that association coefficients may have in general, e.g., zero value under statistical independence, and we examine coefficients for 2x2 tables with respect to these properties. Furthermore, we study a family of coefficients that are linear transformations of the observed proportion of agreement given the marginal probabilities. This family includes the phi coefficient and ...
The aim of this study was to assess the repeatability of an observational gait analysis score that was developed specifically for unilateral amputees. Ten videotaped sequences were analysed by six experienced observers on two separate occasions. Data were analysed using percentage agreement, the kappa statistic and the coefficient of repeatability. The score demonstrated good intraobserver repe...
BACKGROUND This study was designed to measure inter-observer variation between thoracic radiologists in the diagnosis of diffuse parenchymal lung disease (DPLD) using high resolution computed tomography (HRCT) and to identify areas of difficulty where expertise, in the form of national panels, would be of particular value. METHODS HRCT images of 131 patients with DPLD (from a tertiary referra...
Introduction: Measuring level of disability in elderly in attention to their physical status requires an instrument practicable in elderly and easy to score. Objective: Survey the reliability and validity of the HAQ 8-item DI in older people residing in Kashan Golabchi nursing home. Methods: In this methodological study, samples were chosen by census...
There have been few studies that evaluate the reliability of the clinical use of pulse diagnosis despite it being a fundamental part of Oriental medicine diagnostics. The objective of this study was to determine the levels of intra-rater and inter-rater reliability of practitioners using an operationally defined method, Contemporary Chinese Pulse Diagnosis (CCPD), to evaluate the radial pulse o...
OBJECTIVE This research was designed to identify the validity and reliability of the Prescreening Developmental Questionnaire 2 (PDQ-II) in Tehran in comparison with the Denver Developmental Screening Test-II (DDST-II). METHODS After translation and back translation, the final Persian version of test was verified by three pediatricians and also by reviewing relevant literature for content val...
[Purpose] This study aimed to examine the inter- and intra-rater reliability and validity of the modified functional ambulation category (mFAC) scale. [Subjects and Methods] The participants were 66 stroke patients with hemiparalysis. The inter- and intra-rater validity of the mFAC was calculated using the Spearman correlation coefficient. A score comparison of the stable or maximum gait speed ...
