The risk of bias was systematically assessed using an adapted version of the Knowledge Translation Program's prediction worksheet criteria. In accordance with these requirements, three categories were considered.
*
Was a well-defined, representative sample of patients assembled at a common and early point in the course of their disease?
**
Was patient follow-up sufficiently long?
***
Given the large number of factors identified in the various studies, the fact that a multivariate or stratified analysis was performed was already considered positive.
