Robotic liver surgery for metastatic disease: A review of safety, feasibility, and outcomes

Table 6 Methodological quality (Assessment of Multiple Systematic Reviews 2 assessment)

Ref.	Confidence rating	Key strengths	Key limitations
Safiejko et al[6]	Moderate	Direct RLR vs LLR comparison	Retrospective dominance, no RCTs
Machairas et al[7]	Low	Focus on SRAR	Small cohort, no comparator group
Mkabaah et al[9]	High	Large sample, subgroup analyses	Heterogeneity in study designs
Ho et al[12]	Low	Early RLR adoption data	Outdated, mixed malignancies included
McGuirk et al[13]	Low	Detailed technical insights	Small sample, case series bias

RLR: Robotic liver resection; LLR: Laparoscopic liver resection; SRAR: Simultaneous robotic resections; RCT: Randomized clinical trial.
