1 · What the graph read from 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.

2 · The registry

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

backgroundSeveral studies have suggested that laparoscopic liver resection (LLR) is associated with fewer postoperative complications than open liver resection (OLR) for hepatocellular carcinoma (HCC). However, this issue remains controversial since the data may have been attributable to an imbalance in patients' background.

methodsWe retrospectively analyzed 290 hepatectomies for HCC undertaken between 2011 and 2019. Liver resection difficulty was based on the 3 levels of the Institut Mutualiste Montsouris classification. Resection ratio was calculated using computed tomography volumetry. Patient characteristics were compared between the LLR and OLR groups. Propensity score matching (PSM) was adopted to adjust the imbalance between the cohorts, and the incidence of postoperative complications was compared.

resultsThe difficulty and resection ratio were significantly lower in LLR (n = 112) than in OLR (n = 178) (difficulty grade I/II/III: 84/10/18 vs. 43/39/96, p < 0.001; resection ratio: 11.4 ± 12.7 vs. 22.7 ± 17.2%, p < 0.001). The incidence of postoperative complications (Clavien-Dindo grade III or more) was lower in LLR (2.7% vs. 21.9%, p < 0.001), which was mainly attributable to fewer incidences of ascites and pleural effusion. PSM generated 68 well-matched patients in each group. The lower incidence of postoperative complications in LLR was also maintained in the PSM cohort (2.9% vs. 16.2%, p = 0.017). On multivariate analysis, LLR was the independent predictor of postoperative complications (OR 0.184, 95% CI 0.051-0.672, p = 0.010).

conclusionThe present study demonstrated that a laparoscopic approach reduces the incidence of postoperative complications in liver resection for HCC.
