Once such abstraction has been adopted, a large number of graph-theoretical concepts and measures become available for studying and quantifying the topology of the graph.
An initial assessment can be made as soon as data on some measures become available and would continue to be reviewed and revised as the data warrant.
To examine the association between DCD and fitness and adiposity, longitudinal growth models will be fitted with fixed effects for gender, baseline age, DCD status, ADHD symptoms (as these measures become available), time, and time by DCD.
As new versions of these widely used HRQL measures become available, such as a 5-level version of the EQ-5D, further comparisons - particularly using longitudinal data - will be useful in understanding the psychometric strengths and weaknesses of generic and disease-specific HRQL measures for the assessment and monitoring of COPD patient outcomes.
In defining the study cohort, we excluded the first year (i.e. 2004) in which the M1b measure became available in order to avoid possible coding problems that could have arisen as cancer registries gained familiarity with furnishing the M1b code.
The possibility that PN recipients were sicker cannot be ruled out and until a severity of illness measure becomes available, this will always temper interpretations regarding parenterally fed patients undergoing SCT.
Commercial assays to measure HbA1c became available in 1978 (22, 23), and the test gained popularity during the 1980s.
Baseline total expenditures were also modeled because they are highly correlated with expenditures in the next year and were used to control for unobserved health status differences in expenditure analyses until risk adjustment measures became widely available.
In recent years, high-resolution expression data measured in mammalian brains became available in quantities and qualities never witnessed before (Henry and Hohmann, 2012; Lein et al., 2007; Ng et al., 2009), calling for new ways to analyze neural gene expression images.
