Collection system variables of participants in epidemiological studies

摘要

The object of the invention is a system for collecting optimized variables involved in epidemiological studies by an electronic device for collecting variables so that numerous biases that are usually present in such studies are removed. It also allows the information collected from tipping over to a computer for further analysis by the research team. In addition, the system includes important new feature of the possibility that such data (strictly anonymous) remain available for any other researcher. # In this way, the use of this new invention may represent a marked improvement in epidemiological methodology, redound to his once in a major advance in health research: greater control of bias, the greater applicability of the results and conclusions, minor limitations in the studies, fewer participants, lower research costs, shorter studies, etc. .
