Table 3.

The parameter estimates as well as standard errors and p-values for the meta-regression analysis are shown. In this analysis, MRI type and MRI time were both statistically significant at a 95% confidence level. Note that, while pCR has a statistically significant coefficient, this parameter is used in the calculation of sensitivity, specificity, and diagnostic odds ratio, rather than having an interpretation of its own.
