Since most of our knowledge about the epidemiology of T2D in the pediatric population was based on small clinic-based reports, NIDDK partnered with the Centers for Disease Control and Prevention CDCC) to establish the SEARCH for Diabetes in Youth Study to provide population-based statistics for diabetes in U.S. youth (1).
The hypothesis, that gypsies would be less bothered by road traffic noise than the settled population, was based on consideration of the importance of the road in gypsies' lives, and on a small pilot study.
The target student population was based on target age rather than school grade levels to allow for international comparability.
The selection of the study population was based on diagnostic codes established by the International Classification of Diseases, 10th Revision, German Modification (ICD-10-GM).
The identification of the study population was based on the International classification of diseases, 10th revision (ICD-10) diagnoses codes and prescription data.
The final decision rule for our population was based on the following elements: 1) age ≥55 years, 2) inability to continue activity after trauma, 3) support injured wrist by contralateral hand for pain relief, 4) wrist deformity, 5) swelling and/or hematoma and 5) reduced range of wrist motion.
The main study population was based on Gordon setters.
Rejection of the null hypothesis, that responses to paired treatments were drawn from the same population, was based on observed values of the statistic exceeding the 95th percentile of the null distribution.
The simulated population was based on Gaussian distributions of the risk factors but results are robust to changes in these distributions, for example, the results were not altered if all the risk factors were regarded as log-Gaussian.
In the present work, the study population was based on a sub-cohort of 1254 subjects randomly selected from the source sample totalling 8,414 individuals (i.e. a sampling ratio of 15%) stratified by centre, 5-year age class and gender.
The target population was based on convenience sampling.
