Table 2. Sequence of models fitted together with Deviance Information Criteria (DIC).

Model	Description	DIC
Model 0	All tests have equal sensitivity and specificity.	10, 028
Model 1	Sensitivity and specificity vary by test but not location or time.	9, 183
Model 2	Sensitivity and specificity vary by test and location but not time.	7, 576
Model 3	Sensitivity and specificity vary by test, location and time.	6, 149
