	Bayesian bivariate non-hierarchical model	BHLM no covariates	BHLM with covariates
Differential cost (UK pounds): ${\widehat{\Delta }}_c$	8.2 (-32.9 to 50.1)	11.9 (-192.8 to 217.1)	10.3 (-200.4 to 222.1)
Mean life expectancy#: ${\widehat{\eta }}_c$	—	—	11.7 (-74.8 to 98.7)
Survival gain (days): ${\widehat{\Delta }}_e$	24.9 (0.2 to 51.2)	40.2 (-50.9 to 132.8)	35.2 (-64.8 to 136.6)
Public expenditure in health*,#: ${\widehat{\eta }}_e$			52.6 (-18.9 to 124.7)
Between-country variance in differential cost: ${\widehat{\tau }}_c^2$	—	61 (42 to 117)	71 (42 to 155)
Between-country variance in survival gain: ${\widehat{\tau }}_e^2$	—	31 (18 to 73)	12 (7 to 31)

^§Results are reported for four different models: Coefficients and 95% confidence (credibility) intervals (in parentheses). N = 3061. MCMC estimates are obtained after 40,000 iterations and a 20,000 iterations burn-in period
