Patient characteristics as predictors of alcohol use disorder treatment outcome were examined on three levels, identifying whether or not variables were significant predictors of drinking-related outcome in univariate analysis, in multivariate analysis, and in multivariate analyses limited to studies including several "key predictors." Also, a model was developed to predict total percentage of ...
BACKGROUND Although several prognostic genomic predictors have been identified from independent studies, it remains unclear whether these predictors are actually concordant with respect to their predictions for individual patients and which predictor performs best. We compared five prognostic genomic predictors, the V7RHS, the ColoGuideEx, the Meta163, the OncoDX, and the MDA114, in terms of pr...
The flexibility of PLS algorithm can be used to assign suitable weights to predictors or to objects or to both predictors and objects. Weights of predictors are obtained from the regression coefficients and the standard deviation. Weights of objects are obtained from the prediction residuals. By iterative weighting, the regression models are refined and a steady state is attained, where useless...
Stochastic search variable selection (SSVS) algorithms provide an appealing and widely used approach for searching for good subsets of predictors while simultaneously estimating posterior model probabilities and model-averaged predictive distributions. This article proposes a two-level generalization of SSVS to account for missing predictors while accommodating uncertainty in the relationships ...

Objectives: The purpose of this study was examining the accuracy of predictability of cognitive-social variables of life satisfaction in university students. Method: In this analytical-descriptive study, 460 students (243 female and 217 male) of bachelor’s and master’s degree in Uromia University were selected through multistage sampling method and participated in the study. In this study,...
Background and Objectives: Smoking is one of the main causes of various diseases. Due to an increasing trend of smoking among university students, we sought to determine the predictors of adoption of smoking preventive behaviors in university students using the Health Belief Model (HBM). Materials and Methods: This descriptive and analytical study was conducted on 340 students residing in dorm...
Abstract Introduction: Overweight and obesity is one of health related problems that its prevalence in developed and developing countries is on rise and has become a public health problem. Objective: This study aimed to determine the predictors of overweight and obesity in children beginning elementary schools in the city of Rasht. Methods: This descriptive cross - sectional study was conducted...
IntroductionChildren with severe asthma attack are a challenging group of patients who could be difficult to treat and leading to significant morbidity and mortality. Asthma attack severity is qualitatively estimated as mild, moderate and severe attacks and respiratory failure based on conditions such as respiration status, feeling of dyspnea, and the degree of unconsciousness. part of which ar...
Background: Little is known about trends and predictors of hardware related infection following open reduction and internal fixation (ORIF) of extremity fractures, one of the major causes of failure following ORIF. The present study was designed and conducted to determine trends and predictors of infection-related hardware removal following ORIF of extremities using a nationally representative...
