TL;DR: Mortality was most closely associated with right ventricular hemodynamic function and can be characterized by means of an equation using three variables: mean pulmonary artery pressure, mean right atrial pressure, and cardiac index.
Journal ArticleDOI
Long-term effects of budesonide or nedocromil in children with asthma.
Stanley J. Szefler,Scott T. Weiss,James Tonascia,N. Franklin Adkinson,Bruce G. Bender,Reuben M. Cherniack,Michele Donithan,H William Kelly,J. Reisman,Gail G. Shapiro,Alice L. Sternberg,R.C. Strunk,Virginia S. Taggart,Mark L. Van Natta,Robert A. Wise,Margaret Wu,Robert S. Zeiger +16 more
TL;DR: In children with mild-to-moderate asthma, neither budesonide nor nedocromil is better than placebo in terms of lung function, but inhaled budesonides improves airway responsiveness and provides better control of asthma than placebo or nedOCromil.
Journal ArticleDOI
Outcomes of a Field Trial to Improve Children's Dietary Patterns and Physical Activity: The Child and Adolescent Trial for Cardiovascular Health (CATCH)
Russell V. Luepker,Cheryl L. Perry,Sonja M. McKinlay,Philip R. Nader,Guy S. Parcel,Elaine J. Stone,Larry S. Webber,John P. Elder,Henry A. Feldman,Carolyn C. Johnson,Steven H. Kelder,Margaret Wu +11 more
TL;DR: The CATCH intervention was able to modify the fat content of school lunches, increase moderate-to-vigorous physical activity in PE, and improve eating and physical activity behaviors in children during 3 school years.
ReportDOI
Estimation and Comparison of Changes in the Presence of Information Right Censoring by Modeling the Censoring Process.
Margaret Wu,Raymond J. Carroll +1 more
TL;DR: In this paper, a linear random effect model with a probit model for the right censoring process is used to estimate the expected rates of change and the parameters of the right process.
Journal ArticleDOI
Three-Year Maintenance of Improved Diet and Physical Activity: The CATCH Cohort
Philip R. Nader,Elaine J. Stone,Leslie A. Lytle,Cheryl L. Perry,Stavroula K. Osganian,S.H. Kelder,Larry S. Webber,John P. Elder,D.H. Montgomery,Henry A. Feldman,Margaret Wu,Carolyn C. Johnson,Guy S. Parcel,Russell V. Luepker +13 more
TL;DR: This 3-year follow-up without further intervention suggests that the behavioral changes initiated during the elementary school years persisted to early adolescence for self-reported dietary and physical activity behaviors.
