Robotic-assisted donor and recipient hepatectomy in liver transplantation: An umbrella review of clinical outcomes, surgical performance, and cost-effectiveness

Figure 3 Context-only overlay from Broering et al[24] in 2024 (MIOT). Liver-related pooled estimates from Broering et al[24] (systematic review with meta-analysis, MIOT) are shown as a contextual overlay to illustrate concordance in direction/magnitude with the transplant-focused syntheses. These contrasts aggregate transplant and non-transplant settings and are not included in Figure 2 and are not used for AMSTAR/grading of recommendations assessment, development and evaluation certainty to avoid indirectness and overlap. Markers and 95%CIs use the same scales as Figure 2 and are rendered with a distinct symbol/shade.
