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

purposeLaparoscopic left lateral sectionectomy (LLLS) is a feasible and safe procedure with a relatively smooth learning curve. However, single-incision LLLS requires extensive surgical experience and advanced techniques. The aim of this study is to report the standardized single-incision plus one-port LLLS (reduced port LLLS, RPLLLS) technique and evaluate its safety, feasibility, and effectiveness for junior surgeons.

methodsBetween January 2008 and November 2020, the clinical records of 49 patients who underwent LLLS, divided into the conventional LLLS (n = 37) and the RPLLLS group (n = 12), were retrospectively reviewed. The patient characteristics, pathologic results, and operative outcomes were evaluated.

resultsA history of previous abdominal surgery in the RPLLLS group was significantly high (56.8% vs. 91.7%, p = 0.552). Notably, junior surgeons performed 62.2% of the conventional LLLSs and 58.4% of the standardized RPLLLSs. There were no significant differences between the two groups in terms of median operative time (121.0 vs. 113.5, p = 0.387), median blood loss (13.0 vs. 8.5, p = 0.518), median length of hospital stays (7.0 vs. 7.0, p = 0.408), and morbidity rate (2.7% vs. 0%, p = 0.565), respectively.

conclusionThis standardized RPLLLS is a feasible and safe alternative to conventional LLLS and may become the ideal training procedure for both junior surgeons and surgeons aiming to learn more complex procedures.
