Using specifications developed for geographical gazetteers as a starting point, I have developed a content specification for time period directories, including a thesaurus of time period categories (such as a period of rule or a cultural movement), and have implemented a prototype directory.
Data was broken down into three period categories and resistance rates at 10-year intervals were analyzed.
The SeBCS cases and controls were frequency matched by 5-year age and three enrollment period categories (1993 1997, 1998 2000, and 2001 2007).
We calculated these expected counts by apportioning each woman's follow-up into 5-year age and calendar period categories, thereby accounting for differences associated with these variables.
The total number of months spent in drought was similar across the 'constant' drought and the 'constant drought with recent long period' categories.
To determine the expected numbers, person years at risk by 5-year age categories and 1-year calendar period categories were multiplied with the corresponding background cancer incidence in the general Dutch female population and then summed up.
In apportioning person-years to specific age-race-sex-and calendar period categories for each base, once an individual was stationed at Camp Lejeune (e.g., some began at Camp Pendleton and later transferred to Camp Lejeune), all subsequent person-years were assigned to Camp Lejeune.
b MRR estimares are adjusted for age, calendar period, residence category or job category, and time since first employment.
In all adjusted analyses, the following covariates were considered: age at T1D onset (three categories), calendar period (four categories), and sex.
Table 4 shows the fraction of a representative sample of ~ 10,000 social media mentions over the full ten-year period by category and platform.
