Comparison of laparoscopic versus open liver resection for lesions located in posterosuperior segments: a meta-analysis of short-term and oncological outcomes.
Synthesis in Surgical endoscopy, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 16 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
backgroundThe role of laparoscopic liver resection (LLR) for lesions located in posterosuperior (PS) segments remains a matter of development to be further assessed. This systematic review aims to compare the short-term and oncological outcomes between laparoscopic and open liver resection (OLR) in PS lesions.
methodsEMBASE, MEDLINE and Cochrane Library were searched from date of inception to June 2019. This meta-analysis was performed using the STATA 12.0 statistical software. Standardized mean differences (SMDs), odds ratios (ORs) and hazard ratios (HRs) were calculated for continuous variables, dichotomous variables and long-term variables, respectively, with 95% confidence intervals (CIs).
resultsA total of 788 patients from eight studies were identified for the final analysis, with 371 patients in the LLR group and 417 in the OLR group. Although the operation time (SMD 0.22; 95% CI 0.08-0.36; P = 0.003) was longer whereas overall complication rate (OR 0.50; 95% CI 0.36-0.70; P < 0.001) and postoperative hospital stay (SMD - 0.45; 95% CI - 0.59 to - 0.30; P = 0.003) were lower in the LLR group than in the OLR group, no significant differences in blood loss (SMD - 0.14; 95% CI - 0.28 to 0.00; P = 0.054), transfusion rate (OR 0.92; 95% CI 0.56-1.54; P = 0.764), major complication rate (OR 0.63; 95% CI 0.38-1.05; P = 0.079), R0 resection rate (OR 1.04; 95% CI 0.55-1.96; P = 0.902), and disease-free survival (DFS) for hepatocellular carcinoma (HCC) (HR 1.43; 95% CI 0.95-2.17), DFS for colorectal liver metastases (HR 1.05; 95% CI 0.61-1.81), overall survival for HCC (HR 1.00; 95% CI 0.43-2.30) were noted between the groups.
conclusionLLR is technically feasible and safe without compromising long-term oncological outcomes for selected patients with lesions in the PS segments of the liver.
