Background:
Pilot project
A pilot study was conducted between June 2010 and February 2011, prior to the final project, whose first preliminary results are presented in this report. The aims of this study were:
• To verify the feasibility of the working procedure, the cooperation of the tar- get population and the adequacy of screening protocols to the study objec- tives.
• To obtain early and sufficient information on the characteristics of the recruit- ed volunteers and those that could not be recruited, as well as the limitations of the actual sampling compared to the intended one.
• To get experience in the implementation of the different elements of the pro- tocol and to estimate the burden of the evaluator and the evaluated.
• To promote the Project to achieve the participation of volunteers and attract- ing enough funds to carry out the Vallecas Project.
175 volunteers were involved in this phase of the project, of which:
• 95 people were able to participate in the project.
• 80 people were unable to participate because they met at least one exclusion criterion.
