abstract this study scrutinized the interaction between linguistic and strategic variables in reading comprehension test performance of iranian efl learners. to this end, the interaction among the participants’ reading comprehension test performance, use of test-taking strategies, and level of language proficiency was analyzed. the participants comprised 286 students who answered a reading comp...

background: the present study was performed to develop a scoring system for predicting cure status in patients with cutaneous leishmaniasis (cl). materials and methods: this study included 199 patients with cl from skin diseases and leishmaniasis research center (isfahan, iran). data were collected as longitudinal in each visit of patients. we applied ordinal logistic generalized estimating equ...

OBJECTIVE To compare the performance of formal prognostic instruments vs subjective clinical judgment with regards to predicting functional outcome in patients with spontaneous intracerebral hemorrhage (ICH). METHODS This prospective observational study enrolled 121 ICH patients hospitalized at 5 US tertiary care centers. Within 24 hours of each patient's admission to the hospital, one physic...

The interrater reliability of the Supports Intensity Scale (SIS) was investigated under the condition that interviewers had to have been trained and/or experienced in its administration and scoring. Both corrected and noncorrected Pearson's product-moment coefficients were generated to assess interinterviewer, interrespondent, and mixed interrater reliability. The correlation coefficients for t...

The aim of this paper is to propose an efficient method for filtrating wavelet coefficients in image compression. The method filtrates coefficients based on wavelet transform, mathematical expectation and standard deviation. Image quality is measured objectively, using peak signal-to-noise ratio, and subjectively, using mean opinion score. Experimental results indicate that this method based on...

OBJECTIVES It has been difficult to monitor the pelvic position during actual daily life. However, recent developments in wearable device technologies, such as the LUMOback device, provide the possibility to evaluate habitual pelvic posture and time spent sitting during daily life. The current study aimed (1) to investigate test-retest reliability for habitual pelvic posture and time spent sitt...

OBJECTIVE Fatigue is a common nonmotor symptom in Parkinson's disease (PD); however, the Parkinson's disease fatigue scale (PFS), which is designed to measure fatigue in PD, has not been validated in China. The aim of this study was to determine the validity and reliability of the Chinese version of the PFS in PD patients. METHODS A total of 115 PD patients were evaluated at baseline and afte...

Classical regression analysis uses partial coefficients to measure the influences of some variables (regressors) on another variable (regressand). However, a descriptive point of view shows that these coefficients are very bad measures of influence. Their interpretation as an average change of the regressand is only valid if the regressors are weakly correlated, and they are useless when the de...

This article considers the quantile regression approach for partially linear spatial autoregressive models with possibly varying coefficients. B-spline is employed approximation of The instrumental variable parameter estimation. rank score tests are developed hypotheses on coefficients, including non-varying coefficients and constancy asymptotic properties proposed estimators test statistics bo...

INTRODUCTION Osteochondral allograft (OCA) transplantation is a suitable treatment option for large osteochondral defects. Magnetic resonance imaging (MRI) is an objective, reproducible, noninvasive monitoring tool for postoperative assessment after cartilage surgery. OBJECTIVE To correlate Osteochondral Allograft MRI Scoring System (OCAMRISS) in patients undergoing OCA transplantation in the...
