Who paid for this research, and does that matter?

Study design: Meta-analysis of randomised trials. Funding: No external funding. Independence from the proponent is not recorded. Industry sponsorship is one of the most reliably measured biases in medicine, which is why funding carries real weight in the score rather than sitting in a footnote.

Is buspirone (Buspar), buspar FDA approved?
