Abstract: Objective To introduce the Bayesian meta-analysis of the diagnostic test using the SAC software PROC MCMC program.Methods Meta-analysis code based on SAS PROC MCMC program prepared by Menke J was used and the study on the accuracy of high-resolution ultrasound diagnosis of anterior disc displacement of temporomandibular joint published by Dong Xiaoyu et al. was selected as an example data. Bayesian meta-analysis implementation method for diagnostic test was introduced.Results Based on the example data, the Results of Bayesian fixed effect model and random effect model meta-analysis were given. The Results of random effects analysis showed that the combined sensitivity, specificity, diagnostic Odds Ratio (DOR)of high-resolution ultrasound diagnosis for anterior disc displacement with reduction (ADDWR) were 0.852 (95%CI: 0.766-0.924), 0.865 (95%CI: 0.760-0.944), 53.413 (95%CI: 11.855-170.4) respectively.Conclusion SAS PROC MCMC was an excellent method for achieving bivariate random effects Bayesian meta-analysis of sensitivity and specificity.
