In the second method, the age of haplotypes carrying derived alleles of SNPs in terms of the number of mutations was measured by the Rho index [27] by means of the program NETWORK version 4.2 (NETWORK website).
By direct method, the age standardized incidence rate (ASIR) of thyroid cancer per 100,000 Canadians has increased from 1.1 in 1970 1972 to 6.1 in 2012 for males, and from 3.3 to 22.2 in females during the same period 1– 14.
The performance of the creep model was identified by creep tests on cylindrical specimens with stepwise loads, and compared with the performance of the effective modulus method, the age-adjusted effective modulus method, the rate-of-creep method, and the step-by-step method.
In the proposed method, the aging and constraining effect of the boundary condition is represented by an artificial rotational spring at each support.
Using this method, the ages of mountain yellow-legged frogs (Rana muscosa) were studied, the phalanges of the toes showing seasonal lines where growth slows in winter.
Based on the AAP/CDC method, the age-standardized prevalence of moderate periodontitis was 373 (95% confidence interval (CI): 342, 404) cases per 1,000 males and 285 (95% CI: 258, 312) cases per 1,000 females.
In the direct method, the age-adjusted rate represents what the rate would be if the study population had the same age distribution as a reference population (i.e., the projected US Census 2000 age distribution).
Under this combined method, the age-adjusted prevalence of moderate-to-severe periodontitis was 496 (95% CI: 464, 528) cases per 1,000 males and 408 (95% CI: 379, 438) cases per 1,000 females.
On the basis of the American Academy of Periodontology/Centers for Disease Control and Prevention method, the age-standardized prevalence of moderate or severe periodontitis (combined) was 407 per 1,000 males and 308 per 1,000 females (348/1,000 males and 269/1,000 females using the CDT code method).
The Análisis Epidemiológico de Datos Tabulados (Epidat, Epidemiological Analysis of Tabulated Data) program, version 3.1 (Pan American Health Organization; http://dxsp.sergas.es) was used for standardize, by the direct method, the age-adjusted crude and mean mortality rates, by subperiod and for the study period as a whole, to the population of Brazil in 2000.
It should be noted that because of the study design (see Methods), the age distributions are the same in the case and control groups, as are the mean ages for case and control groups (Table 1).
