Cure rates were also stratified by country and age (age groups: ≤12 months; >12 months), though the study was not powered for proving efficacy within each country or age group.
To control for the non-linear effect of age, age groups were entered into the model.
Furthermore, data were stratified by age (age groups: 15 24, 25 44, 45 64, and 65+) and gender, where available.
Maternal age (age groups: ≤27 years, 28 32 years, ≥33 years), and height were registered at the first prenatal visit.
†Adjusted for age (age groups <18 y, 18 25 y, >25 y) and sex, except orchitis, which was adjusted only for age.
Women in the youngest (18 20 years of age) and oldest (>50 years of age) age groups represented only 3.9%and7.2%2%, respectively, of all cases (Table).
To match case-patients and controls by age, age groups of 3 5 years (e.g., 2 4, 5 9, and 65 69 years of age) were used.
In the reoperation analyses, a Cox regression model was used to adjust for differences in age (age groups), sex, cognitive function, and comorbidity (ASA classification).
ICERs in the young and middle-age age groups (age 30 and 50) show cost-savings and are thus naturally below the EUR50,000/QALY gained that is routinely used as the threshold value for German health care interventions [ 34].
Women included were in their reproductive age (age group 15-49 years; USA: 18-49 years) and had ever experienced menstrual bleedings.
