The occurrence of PEAC in the proband and his sister was associated with similar clinicopathological features, summarized in Table 1, such as comparable age at diagnosis, smoking history, and identical localization of the tumor.
The subjects in this subgroup indeed showed increased values of the three criteria (size, density, percentage of covered skin surface), at comparable ages and ethnicities as compared to the general population, confirming their own visual assessments.
Rats on restricted diets are able to run mazes more successfully than the well-fed rats at comparable ages.
At comparable ages, 28% to 32% of the youngest boomers were obese.
So far, the other birth cohorts who will remain in this critical age group have displayed higher participation rates than the Kennedy cohort did at comparable ages.
At comparable ages fewer women than men died at home.
In the birth cohorts of 2000 2002 the cumulative incidence even exceeded that of the epidemic cohorts at comparable ages.
The epidemic birth cohorts (1984 1994) maintained the highest cumulative incidence at comparable ages over the entire follow-up period until 2009, and the only exceptions to this pattern were the cohorts of 2000 2002.
On the other hand, comparison with a control, ie, skin free from SP, is a difficult objective since SP affects both cheeks in all subjects, at comparable ages, presenting a symmetric pattern.
As in other studies [ 4], the frequency of BRCA1/ BRCA2 mutations taken together was lower than the estimated frequencies at comparable ages for all susceptibility alleles derived from the CASH study [ 3].
As in other studies, the frequency of BRCA1/ BRCA2 mutations taken together was lower than the estimated frequencies at comparable ages for all susceptibility alleles derived from the Contraceptive and Steroid Hormones (CASH) study.
