OpenBUGS code (.txt file) from the article "Modelling multiple dichotomous outcomes in network meta-analysis"

Models for WinBUGS (.txt file) from the article 'Evaluating the impact of imputations for missing participants outcome data in network meta-analysis'. Published in Clinical Trials.

Models and data for WinBUGS (.odc file) from the article 'Using network meta-analysis to evaluate the existence of small-study effects in a network of interventions' Published in Research Synthesis Methods

Models for WinBUGS (.txt file) and Appendix from the article 'Network meta-analysis models to account for variability in treatment definitions: application to dose effects' (Published in Statistics in Medicine)

WinBUGS code used in the paper "Mavridis D, Sutton A, Cipriani A, Salanti G. A fully Bayesian application of the Copas selection model for publication bias extended to network meta-analysis. Statistics in Medicine 2013; 32(1):51-66."
(The code requires study-level data. The observed effect sizes, the corresponding standard errors and the number of studies.
We also need to assign two probability distributions, one for observing the largest study in the sample and one for the smallest study in the sample. The smallest study has a Uniform distribution on [l1,l2] and the largest study has a Uniform distribution on [u1,u2])
