Web-based system:

• A web-based system is available for large trials. It is possible to combine the IVRS and web access methods.

Costs

Manual service:

Automated services:

A range of methods is available, but most commonly we use minimisation. Stratified blocks are available upon request.

The most appropriate method will be determined after detailed discussion with a statistician and will be based on your trial size, stratification factors and any practical requirements.
