Robotic versus laparoscopic resections of posterosuperior segments of the liver: a propensity score-matched comparison.
Article in Surgical endoscopy, 2016. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 63 papers, 9 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
backgroundOpen parenchymal-preserving resection is the current standard of care for lesions in the posterosuperior liver segments. Laparoscopy and robot-assisted surgery are emergent surgical approaches for liver resections, even in posteriorly located lesions. The objective of this study was to compare robot-assisted to laparoscopic parenchymal-preserving liver resections for lesions located in segments 7, 8, 4a, and 1.
methodsDemographics, comorbidities, clinicopathologic characteristics, surgical treatments, and outcomes from patients who underwent laparoscopic and robot-assisted liver resection in two centers for lesions in the posterosuperior segments between June 2008 and February 2014 were reviewed. A 1:2 matched propensity score analysis was performed by individually matching patients in the robotic cohort to patients in the laparoscopic cohort based on demographics, comorbidities, performance status, tumor stage, location, and type of resection.
resultsThirty-six patients who underwent robot-assisted liver resection were matched with 72 patients undergoing laparoscopic liver resection. Matched patients displayed no significant differences in postoperative outcomes as measured by blood loss, hospital stay, R0 negative margin rate, and mortality. The overall morbidity according to the comprehensive complication index was also similar (34.6 ± 33 vs. 18.4 ± 11.3, respectively, for robotic and laparoscopic approach, p = 0.11). Patients undergoing robotic liver surgery had significantly longer inflow occlusion time (77 vs. 25 min, p = 0.001) as compared with their laparoscopic counterparts.
conclusionsAlthough number and severity of complications in the robotic group appears to be higher, robotic and laparoscopic parenchymal-preserving liver resections in the posterosuperior segments display similar safety and feasibility.
