Synthesizing Evidence

  • Paul-Christian Bürkner
Chapter

Abstract

Synthesizing evidence of diagnostic studies comes with more complications than synthesizing evidence of clinical trials. This is because the performance of diagnostic tests is evaluated for participants who have the target condition as well as for participants who do not have the target condition, usually in terms of sensitivity and specificity, respectively. There is a natural trade-off between sensitivity and specificity as lowering the threshold, at which participants will be diagnosed as positive, will increase sensitivity but at the same time reduce specificity. Thus, appropriate methods for diagnostic meta-analysis deal with pairs of sensitivity and specificity to preserve the bivariate nature of diagnostic accuracy. In the present chapter, we present a number of approaches to diagnostic meta-analysis and focus on the most commonly applied methods that are able to incorporate systematic variation between studies in addition to differences in the applied thresholds.
