Other related information

To evaluate the risk of funding bias in the systematic reviews, we applied the Cochrane Collaborations criteria for assessment5, which includes 5 items from Mandrioli et al5 (i) whether explicit and ell defined criteria that could be replicated by others were used to select studies for inclusion or exclusion in the review (ii) whether there was an adequate study inclusion method, with two or more assessors selecting studies (iii) whether the search for studies was comprehensive and (iv) whether methodological differences and other characteristics that could introduce bias were controlled. Each item will be given a designation of yes, no, or unclear. The overall risk of bias will be considered low if 3 or more of these criteria had been met and high otherwise. Risk of bias will be evaluated at the study level. Results from risk of bias evaluations will be used to evaluate the relationship between systematic reviews at risk of bias, the COI of systematic review authors, and the systematic review sponsor.
