PURPOSE To a) introduce and present the advantages of linear mixed models using generalized least squares (GLS) when analyzing repeated measures data; and b) show how model misspecification and an inappropriate analysis using repeated measures ANOVA with ordinary least squares (OLS) methodology can negatively impact the probability of occurrence of Type I error. METHODS The effects of three s...

Descriptive survey model was used in research. research applied on 240 students playing 1st amateur league, Ordu. ‘Risk Assessment Scale’ developed by Karataş (2012) as a data collection tool. scale scores groups independent variables were compared with t-test, one-way analysis variance ...

OBJECTIVE Evaluate axial mesiodistal inclinations of the mandibular molars in orthodontically treated cases, analyzing whether inclusion of second mandibular molars in treatment mechanics has any influence on final and postretention molars angulations. METHODS The sample comprised 150 panoramic radiographs of 50 patients. Patients were treated with extraction of four first premolars and divid...

Objective: The aim of the present ex-vivo study was to evaluate the effect of the vertical placement angle of mini-implants on primary stability by analyzing maximum insertion torque (MIT). Methods: Mini-implants were placed in 30 human cadavers, inserted at either a 90° or 60° angle to the buccal surface of the maxillary first molar. Out of 60 self-drilling mini-implants used, half were of ...

BACKGROUND Monitoring the functional connectivity between brain regions is becoming increasingly important in elucidating brain functionality in normal and disease states. Current methods of detecting networks in the recorded electroencephalogram (EEG) such as correlation and coherence are limited by the fact that they assume stationarity of the relationship between channels, and rely on linear...

urvival analysis is seldom used in studies of the S of musculoskeletal therapy. Most clinical studies of musculoskeletal therapy use parametric statistical methods such as analysis of variance (ANOVA) to illustrate the effects of treatment on outcomes. Nonparametric techniques of analysis such as survival analysis are less frequently used. Survival analysis has a number of advantages that make ...
