Specific questions for prospective solutions:

• Is the solution promising enough?

Specific questions for retrospective observational studies:

• What is the data source and how was the solution attained?
• Is the cohort well described and reasonably homogeneous?
• Have attempts been made to account for biases inherent in retrospective reviews?
• What statistical methods were used?
• Are the conclusions appropriate to the study design?
