Deterministic method of allocation
A method of allocating participants to interventions that uses a pre-determined rule without a random element (e.g., alternate assignment, based on day of week, hospital number, or date of birth).
Because group assignments can be predicted in advance of assignment in deterministic methods, participant allocation may be manipulated, causing selection bias.
