EVALUATING DATA QUALITY OF CLINICAL TRIALS

摘要

An analysis server obtains data associated with patients as part of a clinical trial. The analysis server derives models from the patient data, the models specifying how likely it is that a given value of a variable (or values of a pair of variables) are erroneous. The models can be applied to the patient data to identify variable values more likely to be erroneous, and in turn to assess the data quality of patients, sites, and the clinical trial itself.
