Why did you start?

‘Few principles are more fundamental to the scientific and ethical validity of clinical research than that studies should address questions needing to be answered, and that they are designed in a way that will produce a meaningful answer.

A prerequisite for either of these goals is that relevant prior research be properly identified. . . . An incomplete picture of pre-existing evidence violates the implicit ethical contract with research participants that the information they provide is necessary and will be useful to others.’
