Figure 1.

Comparing the arm-based and contrast-based models according to log odds ratio changes. In the upper two panels, single-arm studies are kept in the reduced networks for the arm-based model; in the lower panels, the arm-based model is applied only to studies that can also be used by the contrast-based model, i.e., single-arm studies are excluded. Left panels are scatterplots of all log odds ratio changes (${\mathrm{LORC}}_{ij}^{(-k)}$) in the fourteen networks under the contrast-based model (vertical axis) vs. those under the arm-based model (horizontal axis). Right panels show the empirical cumulative distribution function of log odds ratio changes under the two models.
