Laparoscopic versus open in right posterior sectionectomy: a systematic review and meta-analysis.
Synthesis in Langenbeck's archives of surgery, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Cited by 4 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
backgroundLaparoscopic liver resection (LLR) is now widely adopted for the treatment of liver tumors due to its minimally invasive advantages. However, multicenter, large-sample population-based laparoscopic right posterior sectionectomy (LRPS) has rarely been reported. We aimed to assess the advantages and drawbacks of right posterior sectionectomy compared with laparoscopic and open surgery by meta-analysis.
methodsRelevant literature was searched using the PubMed, Embase, Cochrane, Ovid Medline, and Web of Science databases up to September 12, 2021. Quality assessment was performed based on a modified version of the Newcastle-Ottawa Scale (NOS). The data were analyzed by Review Manager 5.3. The data were calculated by odds ratio (OR) or mean difference (MD) with 95% confidence intervals (CI) for fixed-effects and random-effects models.
resultsThe meta-analysis included seven studies involving 739 patients. Compared with open right posterior sectionectomy (ORPS), the LRPS group had lower intraoperative blood loss (MD - 135.45; 95%CI - 170.61 to - 100.30; P < 0.00001) and shorter postoperative hospital stays (MD - 2.17; 95% CI - 3.03 to - 1.31; P < 0.00001). However, there were no statistically significant differences between LRPS and ORPS regarding operative time (MD 44.97; P = 0.11), pedicle clamping (OR 0.65; P = 0.44), clamping time (MD 2.72; P = 0.31), transfusion rate (OR 1.95; P = 0.25), tumor size (MD - 0.16; P = 0.13), resection margin (MD 0.08; P = 0.63), R0 resection (OR 1.49; P = 0.35), recurrence rate (OR 2.06; P = 0.20), 5-year overall survival (OR 1.44; P = 0.45), and 5-year disease-free survival (OR 1.07; P = 0.88). Furthermore, no significant difference was observed in terms of postoperative complications (P = 0.08), bile leakage (P = 0.60), ascites (P = 0.08), incisional infection (P = 0.09), postoperative bleeding (P = 0.56), and pleural effusion (P = 0.77).
conclusionsLRPS has an advantage in the length of hospital stay and blood loss. LRPS is a very useful technology and feasible choice in patients with the right posterior hepatic lobe tumor.
