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

backgroundAlthough laparoscopic hepatectomy has been proven to be safe and reliable, the influence of tumor size on the feasibility of laparoscopic left lateral segmentectomy (LLLS) is unclear. We retrospectively reviewed our surgical results focusing on hepatic tumor located in the left lateral segment.

methodsFrom January 2003 to June 2016, patients who underwent left lateral segmentectomy were retrospectively reviewed, and data were collected on patient characteristics, peri-operative outcomes, and pathologic results. Patients with intrahepatic stone, cystic lesion, or unmeasurable tumor size were excluded. The continuous variables were compared using the Mann-Whitney U test and categorical variables using the Chi square or Fisher's exact test. The overall and disease-free survival rates were computed using the Kaplan-Meier method and compared using the log-rank test.

resultsA total of 103 patients were enrolled for analysis. Among the patients with tumors larger than 5 cm in the left lateral segment, those who underwent laparoscopic surgery had significantly shorter hospital stay and larger resection margin than those who underwent open surgery. The surgical results of the patients who underwent LLLS were not significantly different from those of the patients with tumors larger than 5 cm. Specifically, the 5-year overall survival and disease-free survival rates of the patients with hepatocellular carcinoma (HCC) larger than 5 cm who underwent LLLS were comparable to those of the patients who underwent open left lateral segmentectomy.

conclusionsLLLS is safe and also feasible for hepatic tumors larger than 5 cm. For HCCs larger than 5 cm, the laparoscopic approach yields satisfying oncologic outcomes as the open approach.
