Confidence intervals for directly standardized rates: a method based on the gamma distribution
Michael P. Fay,Eric J. Feuer +1 more
TL;DR: This work offers an approximation to central confidence intervals for directly standardized rates, where it is assumed that the rates are distributed as a weighted sum of independent Poisson random variables.
Journal ArticleDOI
The Role of Fish Predation and Spatial Heterogeneity in Determining Benthic Community Structure
TL;DR: The effects of predation and spatial heterogeneity on the benthic macroinvertebrates in the littoral zone of a pond were investigated in a year-long caging experiment, finding that the added physical complexity serves as a refuge from predation.
Journal ArticleDOI
Variations in oxidative susceptibility among six low density lipoprotein subfractions of differing density and particle size.
TL;DR: The positive association of T1/2max with unesterified cholesterol suggests that this constituent may impart resistance to oxidative modification, possibly by altering properties of the surface monolayer where it resides.
Journal ArticleDOI
Hypertension and sudden death: Increased ventricular ectopic activity in left ventricular hypertrophy☆
TL;DR: Electrocardiographic monitoring of patients with left ventricular hypertrophy allows identification of those who have the highest risk and, therefore, require the most aggressive therapeutic intervention.
Journal ArticleDOI
Hemodynamic Predictors of Myocardial Oxygen Consumption During Static and Dynamic Exercise
Richard R. Nelson,Fredarick L. Gobel,Charles R. Jorgensen,Kyuhyun Wang,Yang Wang,Henry Longstreet Taylor +5 more
TL;DR: The readily measured variables of heart rate and ofHeart rate × blood pressure correlated well with MVO2 in normal young men during exercise under a wide variety of circumstances.
