OBJECTIVES To establish the percent change in disability index as an outcome measure able to identify risk factors for poor results in lumbar spina...
متن کاملThe use of percentage change from baseline as an outcome in a controlled trial is statistically inefficient: a simulation study
BACKGROUND Many randomized trials involve measuring a continuous outcome - such as pain, body weight or blood pressure - at baseline and after treatment. In this paper, I compare four possibilities for how such trials can be analyzed: post-treatment; change between baseline and post-treatment; percentage change between baseline and post-treatment and analysis of covariance (ANCOVA) with baselin...
متن کاملActivation of protease-activated receptor (PAR)-1, PAR-2, and PAR-4 stimulates IL-6, IL-8, and prostaglandin E2 release from human respiratory epithelial cells.
Epithelia from many tissues express protease-activated receptors (PARs) that play a major role in several different physiological processes. In this study, we examined their capacity to modulate IL-6, IL-8, and PGE(2) production in both the A459 and BEAS-2B cell lines and primary human bronchial epithelial cells (HBECs). All three cell types expressed PAR-1, PAR-2, PAR-3, and PAR-4, as judged b...

The theory of Teaching for Abstraction was used to construct a unit for teaching percentages in Grade 6. The unit focused on percentage as a multiplicative relationship and put more emphasis on why percentages are used than on how they are calculated. Analysis of the data collected showed that many students did learn to apply percentages meaningfully, although the level of achievement was not a...
متن کاملHemolytic Anemia as an Outcome of Occupational Exposure to Formalin: A Case Report
ABSTRACT Background: Occupational exposure studies indicate that formaldehyde exposure causes temporary and consistent effects on industrial workers exposed to formalin. Case: The case was a 36-year-old man who had developed intravascular hemolytic anemia caused by formalin after inhalation exposure. Formalin is a clear solution of 37% formaldehyde in water.
