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

backgroundMany studies demonstrated the feasibility of laparoscopic liver resection (LLR). However, its short-term outcomes for liver malignancies located in involving Couinaud's segment 7 have not been appraised compared to open liver resection (OLR). In addition, the impact of the LLR learning curve on surgical outcomes at these sites remains unclear.

methodsThis single-institution, retrospective study included 216 patients who underwent liver resection for malignancies involving segment 7 between 2010 and 2024. Propensity score matching balanced LLR (n = 65) and OLR (n = 65) cohorts. Surgical outcomes were compared and the LLR learning curve for conversions was plotted via risk-adjusted cumulative sum (RA-CUSUM) analysis.

resultsLLR showed shorter postoperative hospital stays and a trend towards less blood loss. Despite longer operative times, LLR had lower postoperative white blood cell counts and similar alanine aminotransferase levels. There were no significant differences between the groups in the overall or severe complications. Moreover, RA-CUSUM analysis showed that after the surgeon completed around 30 patients, the conversion rate stabilized and improved, leading to enhanced safety.

conclusionsLLR could act as a safe alternative to OLR in patients harboring malignancies involving segment 7, with accumulated experience contributing to improved outcomes.
