- Parallel assignment: A type of intervention model describing a clinical trial in which two or more groups of participants receive different interventions. For example, a two-arm parallel assignment involves two groups of participants. One group receives drug A, and the other group receives drug B. So during the trial, participants in one group receive drug A "in parallel" to participants in the other group, who receive drug B.

- QUOTE: In a parallel design, we are assigning patients and administering treatment, so that the experimental and control groups are in parallel. In other words, we are assigning people to both groups, over the same period of time, as opposed to collecting data on the experimental groups only, and comparing that data to historical controls, or as opposed to assigning treatment A and then assigning treatment B in series.
Each person in a parallel design is assigned to only one treatment group. The process by which we allocate people to a specific treatment group is usually a randomization process. We use randomization to allocate patients because it removes bias in the allocation process, which is called selection bias.
