Level 2a evidence comparing robotic versus laparoscopic left lateral hepatic sectionectomy: a meta-analysis.
Synthesis in Langenbeck's archives of surgery, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 papers, 2 of them syntheses that pooled it.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectivesTo evaluate comparative outcomes of robotic and laparoscopic left lateral hepatic sectionectomy (LLS).
methodsA systematic search of PubMed, Web of Science, EMBASE and bibliographic reference lists with application of a combination of free text and controlled vocabulary search adapted to thesaurus headings, search operators and limits was conducted. Overall, minor (Clavien-Dindo grade < III) and major (Clavien-Dindo grade > III) postoperative complications, mortality, volume of blood loss, conversion to an open procedure, procedure time, length of hospital stay, cost-effectiveness and R1 resection were the evaluated outcome measures.
resultsSeven comparative observational studies reporting a total of 319 patients of whom 150 underwent robotic LLS and the remaining 169 patients underwent laparoscopic LLS were included. The robotic approach was associated with significantly longer procedure time (MD: 29.40 min, p = 0.01) and higher cost (MD: $4170, p < 0.00001) compared to the laparoscopic approach. There was no significant difference in overall postoperative morbidity (OR: 1.29, p = 0.62), Clavien-Dindo grade < III (OR: 1.65, p = 0.49), Clavien-Dindo grade > III (OR: 1.18, p = 0.85), perioperative mortality (RD: 0.00, p = 1.00), volume of blood loss (MD: 1.96 mls, p = 0.91), conversion to an open procedure (RD: - 0.02, p = 0.46), length of hospital stay (MD: 0.22 day, p = 0.52) or R1 resection (RD:0.00, p = 1.00) between two groups.
conclusionsMeta-analysis of the best available evidence (level 2) demonstrated that robotic LLS is associated with significantly longer procedure time and higher cost and similar perioperative outcomes compared to the laparoscopic approach. Future randomised studies are required to evaluate short-term perioperative, long-term oncological and surgeon-centred outcomes.
