Summary
The development of science allows us to take up new investigative challenges. Interpretations of results can be difficult if there is no adequate and complete information about investigative methods applied, course of trial and statistical analyses. The CONSORT group proposed a standardized diagram facilitating an accurate presentation of the randomised trial. The EDEN study is an example of the application of this method, where the studied groups, number of participants, and all procedures can be presented. It is helpful to prepare reports and find necessary data. The first part of the diagram describes the course of recruitment, the second part presents data necessary to estimate the course of the study and data about numbers of patients in each timepoint whilst the third part shows the assessment of caregivers. Conclusions: The analysis of the course and correctness of the study is legible if the flow diagram is used. It is useful to find the necessary data for statistical analyses at every stage of study. Permanent control of the study allow the to avoid bias upsetting the course of the study and influencing its quality. It introduces comprehensible and straight forward presentation of the results.
