Adjustment for reporting bias in network meta-analysis of antidepressant trials

Table 2 Comparison of fit and complexity between the 2 adjustment models and the standard NMA model, all applied to published data

	Regression model	Selection model	NMA model
Mean posterior residual deviance ( ${\bar{D}}_{res}$ )	31.4	31.5	34.4
Effective number of parameters (pD)	15.9	14.7	13.9
Deviance Information Criterion (DIC)	47.3	46.2	48.3

Lower values of ${\bar{D}}_{res}$ indicate a better fit to the data. Lower values of the DIC indicate a better compromise between model fit and model complexity. A difference in DICs of 5 or more can be considered substantial (http://www.mrc-bsu.cam.ac.uk/bugs/winbugs/dicpage.shtml).
