Types of outcomes and corresponding link functions and likelihood distributions available within BUGSnet

Type of Outcome	Arm-Level Data Required	Distribution Family	Link function	Measure of effect	Assumption on follow-up time
Continuous	Mean & Standard Error	Normal	Identity	Mean Difference	Outcome is unrelated to follow-up time
Dichotomous	Events & Sample Size	Binomial	Logit	Odds Ratio
			Log	Risk Ratio
	Events & Sample Size & Median Follow-Up Time		Complementary log-log	Hazard Ratio	Event rates are constant over the duration of follow-up
Count	Events & Person-Time at Risk	Poisson	Log	Rate Ratio
