Primary outcome of interest across studies (n = 56) by model type. Categories of the primary outcomes are not mutually exclusive; studies with >1 primary outcome of interest are represented within each applicable category. >1 Type, studies with multiple primary outcomes of interest; ABM, agent-based model; Business, retail outcomes including store revenue and survivability; Cost-effect, cost-effectiveness of simulated policy or intervention; DES, discrete event simulations; Health, population health behavior or outcome; Hybrid, >2 model approaches used; SD, system dynamic models.
