By selecting a sample of first-time-admitted patients, we will avoid the overrepresentation of chronically ill patients.
A sample of first-time arrestees aged under 12 (n = 192) was assessed using the Diagnostic Interview Schedule for Children (DISC-IV) parent-version on attention deficit/hyperactivity disorder (ADHD), oppositional defiant disorder (ODD) and conduct disorder (CD).
The concentrations of these persistent organic pollutants in a sample of first-time pregnant females living in the United States suggest a decline in exposures to these chemicals since their ban or restricted use and emission.
In this study we evaluated the concentrations of selected persistent organic pollutants in a sample of first-time pregnant females residing in the United States and assessed differences in these concentrations in all pregnant females during gestation.
We evaluated the concentrations of persistent organic pollutants in a sample of first-time pregnant females residing in the United States and the changes of these concentrations during gestation for all pregnant women participating in National Health and Nutrition Examination Survey (NHANES) 1999 2002.
However these expectations are often not met as research has shown that a sample of first-time mothers in the U.K. had a range of unmet information needs, such as knowing how frequently to breastfeed, how often to pick up their baby when crying and how often to change their nappy [ 9].
Strengths of our study include the use of population based health administrative data to assemble a large sample of first time recipients of total hip arthroplasty and consideration of patient, hospital, and surgeon predictors of complications after the procedure.
Breast milk concentrations of 32 metals and elements in early lactation (days 14-21) were determined in a random sample of first time Swedish mothers (n = 60) using inductively coupled plasma mass spectrometry (ICPMS).
(c) Multi dimensional scaling (MDS) plot of gene expression for cohort B ADT samples, red is sample of first time point and blue indicates second time point sample, same subject is represented by identical letter.
(c) Multi dimensional scaling (MDS) plot of normalized gene expression for cohort B ADT samples, red is sample of first time point and blue indicates second time point sample, same subject is represented by identical letter.
In this paper the hidden process is first anticipated as a non-stationary Ornstein Uhlenbeck (OU) process with unknown parameters that have to be estimated only by use of the information contained in a sample of first-passage times.
