Assessments of clinical skills of medical students rely increasingly on standardized patients demonstrating medical cases with faculty rating performance. The common finding of inconsistency of scores across cases is often referred to as case…

The relationship between social class and 1980 heart disease (HD) mortality in eight urban U.S. counties was examined by regressing age and sex adjusted census tract specific HD rates (N = 1211) on tract social class characteristics. The regression…

Variation in heart disease (HD) mortality rates across census tracts is greater than expected given binomial error and available explanatory variables. We extended an extra-binomial variation model for rates standardized by the direct method. The…

A method of evaluating trend (positive or negative) in 2 x K ordered tables is suggested for cases in which the scores for the first (K-1) categories are known a priori but the score for the last category is not known. Such a category is termed as…

A randomized clinical experiment to compare two types of endotracheal tubes utilized a block design where each of the six participating anesthesiologists performed tube insertions for an equal number of patients for each type of tube. Five…

Lin and Wang have introduced a quadratic version of the logrank test, appropriate for situations in which the underlying survival distributions may cross. In this note, we generalize the Lin-Wang procedure to incorporate weights and investigate the…

The central nucleus of the inferior colliculus (IC) is a major integrative center in the central auditory system. It receives information from both the ascending and descending auditory pathways. To determine how single IC neurons integrate…

Minimizing margin re-excision optimizes patient care by providing appropriate oncologic resection and reducing costs. This study aims to assess margin positivity rate in two groups: shave margin based on gross specimen (control group, CG) vs shave…

For repeated-measures trials with continuous outcomes in which one group is designated as control and the other treatment, it is sometimes advantageous to add the treatment to the control group in the last periods of the design rather than to…

The field of evolutionary developmental biology is broadly focused on identifying the genetic and developmental mechanisms underlying morphological diversity. Connecting the genotype with the phenotype means that evo-devo research often considers a…

OBJECTIVES: Relatively long digits are considered to enhance grasping performance in primates. We tested whether growth-related changes in intrinsic hand and foot proportions may have behavioral implications for growing animals, by examining whether…
