Just on the different effect sizes from different methods, where do/would RCT methods fit in with the four discussed by Kaats?
FWIW, I agree that a meta-analysis of RCTs isn’t a like-for-like to a single RCT. That said, when(if?) we exhaust the existing SWB literature relevant t cost-effectiveness we should present everything we find (which shouldn’t hard as there’s not much!).
