Location‐Specific Hematoma Volume Predicts Early Neurological Deterioration in Supratentorial ICH

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Early neurological deterioration (END) adversely affects outcomes in patients with intracerebral hemorrhage (ICH). This study aimed to determine the location‐specific hematoma volumes for END in supratentorial ICH patients. Methods We retrospectively analyzed supratentorial ICH patients presenting from two prospective cohorts.

The Source of Lake Wobegon [updated]

Nonpartisan Education Review, 2010
John J. Cannell's late 1980's "Lake Wobegon" reports suggested widespread deliberateeducator manipulation of norm-referenced standardized test (NRT) administrations and results,resulting in artificial test score gains.

Note on the radical inflation in the estimates of error variance in measurement models

Frontiers in Education
This note discusses the radical technical inflation in error variance and the related standard error of test scores from both conceptual and empirical viewpoints. This technical inflation arises as a direct consequence of the technical underestimation of

Determinants of stunting in children under five years in dibate district of Ethiopia: A case-control study

Human Nutrition & Metabolism, 2022
Background: Chronic malnutrition is the consequence of long-term nutritional deficiency resulting in non-communicable disease and reduced productivity in later life. This situation primarily manifests through physical stunting, a term used to individuals

Effective Sample Size: Quick Estimation of the Effect of Related Samples in Genetic Case-Control Association Analyses [PDF]

, 2007
Correlated samples have been frequently avoided in case-control genetic association studies in part because the methods for handling them are either not easily implemented or not widely known.

Score Tests for Semiparametric Zero-inflated Poisson Models

International Journal of Statistics and Probability, 2012
Count data sets often produce many zeros. It is sometimes potentially questionable to use a linear predictor to model the effect of a continuous covariate of interest in zero-inflated count data. To relax the restriction, Li (2011) proposed a semiparametric zero-inflated Poisson (ZIP) regression model by using fixed-knot cubic $basis$ splines or $B ...

A Systematic Comparison of Alpha‐Synuclein Seed Amplification Assays for Increasing Reproducibility

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Seed amplification assays (SAAs) enable ultrasensitive detection of misfolded α‐synuclein across biofluids and tissues. Yet, heterogeneity in protocols limits cross‐study comparability and clinical translation. Here, we review α‐synuclein SAA methods and their performance across various biological matrices.

Advancing Age Modulates Associations Between Cognitive Impairment and Brain Volumes in Early MS

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Introduction Cognitive impairment is common in multiple sclerosis (MS), but manifestations following the first demyelinating event are relatively unexplored. We investigated cross‐sectional associations between magnetic resonance imaging (MRI)–derived brain volumes and the presence of cognitive impairment outcomes five years after the first ...
