Thus, we will first retrace the origins of this policy instrument in the context of the evolution of the external dimension of the EU's migration policy and in the local context of our two main study-cases, Moldova and Georgia.
The main study groups (cases and controls) were comparable regarding age, sex, birth weight, family size, birth order, mother's educational level and socioeconomic class.
In the main study, the case finding algorithm (identified in the SCID sub-study) is applied on the information given in the baseline questionnaire.
The main study is a case study of all the training process of one trainee (John).
Its guidelines provide a user-friendly checklist of 22 items to be reported in epidemiological studies, with items specific to the three main study designs: cohort studies, case-control studies and cross-sectional studies.
During the eligibility period for tier 2 participation, the participation rate in the main study among families of cases < 8 years of age was 86%.
Comparisons were made between the two main study groups (controls and cases) and the three subgroups (controls, acyanotic group and cyanotic group).
For the main study, we used a case-control study design that compared the MA users to a control group of propensity-score matched samples from the National Health and Nutrition Examination Survey NHANESS) [ 12, 13], where propensity scores were used to identify a demographically comparable subset of individuals from the population-based NHANES.
The high-titration case showed a small decrease in the incidence of MACE compared with that in the main study, and the low-titration case showed a slightly increased incidence of MACE compared with that in the main study.
Table 3 records the data of the main study, where one breast cancer case has missing observations and we ignore this in the analysis.
