Both data sources contain information on age, sex, principal diagnosis, external cause and LGA of residence for all cases.
We selected two controls for each case from the eligible source population, matched on age (±1 year), sex, calendar year, and duration of pneumonia-free follow-up (incidence density sampling).
The dataset was extracted from the source administrative data based on age (50+), and therefore patient age is never missing in this analysis.
We accrued 5882 histologically proven cases and 23 517 controls, randomly selected from the source population and individually matched on age and sampling time.
VA administrative data sources are used to provide information on age, sex, and co-morbid conditions (e.g., ICD-9 codes).

In fact, the radiation dose to the bone marrow of children – especially from ingested sources – is some 20 40% higher (depending on age) than in adults (Kendall et al, 2009), so that our estimates (and those of Wakeford et al, 2009) may be a little conservative.
To describe actual data on intake, sources, age and time trends of urinary sodium excretion and to analyze the potential association between urinary sodium excretion and hydration status respective beverage consumption in a sample of healthy German children and adolescents.
In addition, subgroup analyses based on age group, ethnicity, sepsis type, and source of control subjects were performed.
Information on age and sex was known for 290 (92%) and 312 (99%) source patients, respectively.
