We aimed to investigate the effectiveness of our community-based whole food plant-based (WFPB) dietary programme in a population of New Zealanders

The researcher performing measurements was aware of allocation. The participants’ usual health-care providers were not informed of allocation, although they could ask participants. The statistician was blinded.
