Data Management & Statistics

Data Management & 
Statistics

The core of all studies is delivering high quality data. 

Reliable data that can provide us with more knowledge and the pieces of evidence we are looking for and hopefully in the future, provide us with better medical options and treatments. Both statisticians and data managers are key people in the processing of reliable, high-quality data and both must be involved in the project from the early planning to the final closing. How to handle study data starts with the definition of sample size, power calculations, and endpoints and should address potential data issues, that may cause problems later on. 

We mainly use an efficient and fully 21CRF part 11 compliant and validated eCRF solution (Trial-on-Line). A paper-based solution is also an option.
