Table 5 Comparison of Bayesian models ^a

	Random effects
Model	DIC	Heterogeneity SD
Without adjustment	128.29	1.62
Without adjustment excluding studies with no baseline score	107.00	1.53
With adjustment
Baseline	93.85	0.59
Flare	105.32	1.52
Analgesic use	105.88	1.09

^aA lower DIC indicates a better fit of the model. A difference of 3 in the DIC between 2 models is usually meaningful [80].
