Sequence generation, concealment mechanism, implementation of allocation
Practices were randomly selected from the 22 eligible practices that have a moderate to high proportion of Māori, using computer generated random numbers. Randomisation was stratified by practice size and rurality. The randomisation sequence was generated by the trial statistician, blinded to the identity or location of the eligible practices. Researchers working directly with Mahitahi Hauora had no role in the allocation process. The trial statistician assigned the practices based on the randomisation sequence and provided the list of allocated practice numbers to the researchers working with Mahitahi Hauora, who then identified the practices.
