The objectives of this line of projects are to empirically investigate recruitment patterns from about 300 completed or discontinued clinical trials conducted in different countries and settings; to determine optimal time points and criteria for the assessment of recruitment progress in trials; and to develop recruitment prediction tools that are easily applicable for clinical researchers.
