Pooled proportion of medullary thyroid carcinomas (MTCs) classified at high risk/suspicion according to risk stratification systems/thyroid Imaging Reporting And Data Systems (RSSs/TIRADSs). Diamond (yellow for subgroup, blue for the whole group) indicates the pooled proportion and its wideness indicates 95% confidence interval (CI). Square indicates the study sample size and line indicates 95% CI. The studies by Matrone et al., 23 Hahn et al. 24 and Li et al. 27 classified their series of MTCs according to five, two, and two different RSSs/TIRADSs, respectively.
