Propensity score matched comparison of robotic and open major hepatectomy for malignant liver tumors.
Article in Surgical endoscopy, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT06562179 (A Prospective, Single-Center Investigation of the da Vinci SP® Surgical System in Hepatopancreaticobiliary and Foregut Operations for Benign and Malignant Disease.), which is not on this map.

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.

Abstract
backgroundOutcome data on robotic major hepatectomy are lacking. This study was undertaken to compare robotic vs. 'open' major hepatectomy utilizing patient propensity score matching (PSM).
methodsWith institutional review board approval, we prospectively followed 183 consecutive patients who underwent robotic or 'open' major hepatectomy, defined as removal of three or more Couinaud segments. 42 patients who underwent 'open' approach were matched with 42 patients who underwent robotic approach. The criteria for PSM were age, resection type, tumor size, tumor type, and BMI. Survival was individually stratified for hepatocellular carcinoma (HCC), intrahepatic cholangiocarcinoma (IHCC), and colorectal liver metastases (CLM). The data are presented as: median (mean ± SD).
resultsOperative duration for the robotic approach was 293 (302 ± 131.5) vs. 280 (300 ± 115.6) minutes for the 'open' approach (p = NS). Estimated Blood Loss (EBL) was 200 (239 ± 183.6) vs. 300 (491 ± 577.1) ml (p = 0.01). There were zero postoperative complications with a Clavien-Dindo classification ≥ III for the robotic approach and three for the 'open' approach (p = NS). ICU length of stay (LOS) was 1 (1 ± 0) vs. 2 (3 ± 2.0) days (p = 0.0001) and overall LOS was 4 (4 ± 3.3) vs. 6 (6 ± 2.7) days (p = 0.003). In terms of long-term oncological outcomes, overall survival was similar for patients with IHCC and CLM regardless of the approach. However, patients with HCC who underwent robotic resection lived significantly longer (p = 0.05).
conclusionUtilizing propensity score matched analysis, the robotic approach was associated with a lower EBL, shorter ICU LOS, and shorter overall LOS while maintaining similar operative duration and promoting survival in patients with HCC. We believe that the robotic approach is safe and efficacious and should be considered a preferred alternative approach for major hepatectomy.
