Purpose of the study
Educational / counselling / training
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
A computer generated algorithm was used by a researcher (not directly involved in the project) to randomize the patients with the treatment allocation of patients. Those allocated to the intervention were given an appointment to be seen by the intervention staff ( medical officer and trained nurses). Those on the control arm continued to attend the regular monthly clinic.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
