Pure laparoscopic vs. hand-assisted liver surgery for segments 7 and 8: propensity score matching analysis.
Article in Surgical endoscopy, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers, 1 of them a synthesis 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
backgroundLaparoscopic liver resection of tumors located in segments 7 and 8 are considered a complex resection. The aim of this study was to compare the intraoperative and early postoperative outcomes of patients operated by pure laparoscopic (PLS) vs hand-assisted laparoscopic surgery (HALS).
methodsFrom January 2003 to January 2021, we included patients with minimally invasive surgery for lesions located in segments 7 and 8. To overcome selection bias, we performed 1:1 propensity score matching (PSM) between HALS and PLS cohorts, including 30 patients in each of the groups. Of the 60 patients who underwent PSM, we compared the first 30 patients with the following 30 patients.
resultsA total of 79 LLRs were performed, 46 by HALS and 33 by PLS. After PSM, in the PLS cohort, cirrhosis was more frequent (33.3% vs. 13.3%, p = 0.02). The surgical time, blood loss, Pringle maneuver, clamping time, and morbidity were similar between both groups, but with a lower hospital stay in the PLS group (3 days vs. 4 days, p < 0.01). In the first 30 patients who underwent LLR, the use of PLS was lower than the use of HALS, increasing due to the learning curve (16.7% in the first period vs. 83.3% in the second period; p < 0.01). The hospital stay was lower in the second period due to the more frequent use of PLS (3 vs. 4 days, p < 0.01).
conclusionPLS presents similar intraoperative and early postoperative results with lower hospital stay for lesions located in segments 7 and 8 compared to HALS. In centers with experience in LLRs, PLS could be performed safely in these segments.
