Objective: Our purpose was to describe variation in elective primary cesarean rates by nonclinical factors.
Purpose: The primary objective of this study was to characterize variation in patterns of opioid prescribing within primary care settings at first visits for pain, and to describe variation by condition, geography, and patient characteristics.
To describe variation regarding inpatient therapy and evaluation of children with Henoch Schönlein purpura (HSP) admitted to children's hospitals across the United States.
Objectives: To describe variation across Europe in PERISTAT indicators of health care in the perinatal period, and to assess the comparability of these indicators.
As error-fitting function, the Poisson series can describe variation of error with respect to propagation duration and on-orbit position of objects.
To describe variation across US pediatric hospitals in the utilization of resources not recommended for routine use by the American Academy of Pediatrics guideline for infants hospitalized with bronchiolitis and to examine the association between resource utilization and disposition outcomes.
The aims were to establish reliable sampling and recording methods for measuring lying behavior, to evaluate the adequacy of the CCI and SUI as estimates of lying behavior, and to describe variation in the lying behaviors of free-stall-housed dairy cows.
The aim of this paper is to describe variation in the prevalence of lameness and leg injuries, lying behavior, facility design, and management practices for high-producing cows on freestall dairy farms in 3 regions of North America British Columbiaa (BC; n = 42); California (CA; n = 39); and the northeastern United States (NE-US; n = 40).
We adopted a spatial hierarchical approach composed of five spatial levels (km, 100 s m, 10 s m, 1 s m and cm) to describe variation patterns of microphytobenthos, meiobenthos and sediment variables in shallow subtidal regions in the subtropical Paranaguá Bay (Southern Brazil) with live E. emarginata (LE), dead E. emarginata (only skeletons — (DE), and no E. emarginata (WE).
Small plot sizes used in this study are likely limiting the ability to describe variation in light levels and we recommend the use of larger plots (with a radius between 1.0 and 1.7 times tree height) for future studies of this nature.
