Neurophysiological studies are often designed to examine relationships between measures from different testing conditions, time points, or analysis techniques within the same group of participants. Appropriate statistical techniques that can take into account repeated measures and multivariate predictor variables are integral and essential to successful data analysis and interpretation. This wo...

OBJECTIVES To introduce multilevel repeated measures (RM) models and compare them with multilevel difference-in-differences (DID) models in assessing the linear relationship between the length of the policy intervention period and healthcare outcomes (dose-response effect) for data from a stepped-wedge design with a hierarchical structure. DESIGN The implementation of national essential medic...

This study investigated the impact of oral pushed output on the learning and retention of English perfect tenses. During the study, a pre-test was administered to 22 freshmen majoring in English translation. The participants were randomly assigned to two groups. Then, for six sessions both groups received explicit instructions on English perfect tenses. Every session, the experimental group rec...

Background: One of the aesthetic issues in use composite resin is color change. The study aims to compare changes nanofiller before and after immersion red grape juice with different curing durations. Method: This involved 18 round resins a diameter 12 mm thickness 2 mm. sample was divided into three groups (n=6); group A cured for 20 seconds, B 30 C 40 seconds. After curing, samples were immer...

BACKGROUND Tissue engineering represents very exciting advances in regenerative medicine; however, periodontal literature only contains few reports. Emdogain (EMD) consists of functional molecules that have shown many advantages in regenerative treatments. This study investigated EMD effect on gingival fibroblast adhesion to different membranes. MATERIALS AND METHODS Two dense polytetrafluoro...

There has been no study to substantiate the kinematical characteristics of cursor dragging movement. In this present study, we developed a computerized measuring program and used the quantitative experimental research method to explore the effect of moving direction on the kinematics of cursor dragging in 24 normal participants. The results of multiple one way repeated measures ANOVAs and post ...

Introduction: Swallowing disorder or dysphagia is a common complication after conventional total thyroidectomy. Traditional dysphagia therapy (TDT) has long been a routine rehabilitation program for patients with dysphagia; however, there is no evidence to support the efficacy of this approach in patients with post-thyroidectomy dysphagia. Regarding this, the purpose of the current study ...

BACKGROUND Statistical tables are an important component of data analysis and reports in biological sciences. However, the traditional manual processes for computation and presentation of statistically significant results using a letter-based algorithm are tedious and prone to errors. RESULTS Based on the R language, we present two web-based software for individual and summary data, freely av...
