These related to the consent model and the methods of ascertaining, contacting and interviewing participants with breast cancer.
For example, there is no one method of ascertaining if a model's predictions are appropriately close to the validation study endpoints.
The authors marshal an impressive range of methods and employ multiple mouse and cell models to ascertain the presence of disease protein oligomers in susceptible brain tissue/cells and explore interactions between such oligomers and a well-established disease protein interacting partner, Capicua (CIC1).
Thus, we implemented two alternative NMA models to ascertain the impact of this assumption on the relative effectiveness estimates: model C1 used the shape parameter from the first IPD study to describe the AD studies and model C2 used the shape parameter from the second IPD study to describe these same studies.
Based on the results of our previous studies, which had demonstrated that reproductive hormones affect chromatin remodelling, we have further used these hormone-deficient rat models to ascertain the roles of testosterone and FSH in the molecular mechanism underlying the histone to protamine exchange, integral to the condensation of sperm chromatin.
'The exercise of ascertaining the facts was a serious one".
Fifthly, the variable of disposition was incorporated into the multivariable models to ascertain confounding and reverse causality issues.
The authors also have commissioned field research in a sub-Saharan African country to determine the content and face validity of the model to ascertain its relevance as a framework for identifying strengths and weaknesses of current efforts to improve CHW performance, as well as for identifying new opportunities for doing so.
Recent developments include techniques for estimating R 0 from the initial stages of an outbreak [11], [12] and a model to ascertain the effect of a delay between the onset of an outbreak and the implementation of public health policies aimed at controlling disease spread [13].
Life course models representing sensitive periods, accumulation of risk and social mobility were compared with a saturated model to ascertain the nature of the relationship between social class across the life course and each of these novel CHD risk factors.
