BACKGROUND Frontal alpha asymmetry (FAA) has frequently been reported as potential discriminator between depressed and healthy individuals, although contradicting results have been published. The aim of the current study was to provide an up to date meta-analysis on the diagnostic value of FAA in major depressive disorder (MDD) and to further investigate discrepancies in a large cross-sectional...

F rontotemporal dementia (FTD) with amyotrophic lateral sclerosis (ALS) presents with impaired language or behavior and declining motor function. Frontotemporal lobar degeneration with ubiquinated transactivating responsive sequence DNAbinding protein (TDP-43) inclusions is found postmortem in the affected brain areas of patients with ALS, FTD/ ALS, and many patients with FTD. Prior magnetic re...

Journal of Research in Medical Sciences | June 2014 | 580 groups with equal number of persons to increase the power. If not, they should explain about the details of sampling. A sampling frame cannot be assumed. Maybe the possibility of observing significant differences increases between cases with O blood group when they recruit more samples with O blood group. It is a crosssectional study wit...

S erum uric acid is the major product of purine metabolism (1). In crosssectional studies, uric acid correlates with components of the metabolic syndrome: hypertension, obesity, low HDL cholesterol, hypertriglyceridemia, hyperinsulinemia, and insulin resistance (2– 4). Although determination of uric acid is widely available and inexpensive, it has been overlooked as a marker of disturbed glucos...

Parametric dummy variable-based tests for event studies using multivariate regression are not robust to nonnormality of the residual, even for arbitrarily large sample sizes. Bootstrap alternatives are described, investigated, and compared for cases where there are nonnormalities, cross-sectional and time series dependencies. Independent bootstrapping of residual vectors from the multivariate r...
