Key networks for intervention diffusion in big and small venues

Key networks	Large venues	Small venues	Diffusion of intervention information
Top-down networks formed by venue owners/managers to FEWs	✓		Diffusion of information achieved in most of the venues, but also depends on the owner–FEW relationship
Networks between mammies (madams) and FEWs	✓		Diffusion of information obstructed in nearly all the venues due to mammies’ perception of compromised profitability
Networks formed by FEWs working in the same venue	✓	✓	Diffusion occurs but is more location- and context-specific in big venues compared to small venues, where information exchange is less systematic
Networks formed by FEWs from the same city/region	✓	✓	Excellent diffusion of information but is limited in effect size
Networks among close friends	✓	✓	Excellent diffusion of information but may not be easily managed
