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

backgroundPancreatic neuroendocrine neoplasms (PNENs) are increasingly prevalent with modern imaging, and surgical excision remains mainstay of treatment. This study aims to perform a propensity-score-matched (PSM) comparison of perioperative and oncologic outcomes following minimally invasive pancreatectomy (MIP) versus open pancreatectomy (OP) for PNEN.

methodsA retrospective review was performed on patients who underwent curative-intent surgery for PNEN at Singapore General Hospital from 1997 to 2018. A 1:1 PSM was performed between MIP and OP, after which both groups were balanced for baseline variables.

resultsWe studied 134 patients who underwent surgery (36 MIP and 98 OP) for PNEN. Propensity-score-matched comparison between 35 MIP and 35 OP patients revealed that the MIP group had a longer operating time (MD = 75.0, 95% CI 15.2 to 134.8, P = 0.015), lower intraoperative blood loss (MD = - 400.0, 95% CI - 630.5 to - 169.5, P = 0.001), shorter median postoperative stay (MD = - 1.0, 95% CI - 1.9 to - 0.1, P = 0.029) and shorter median time to diet (MD = - 1.0, 95% CI - 1.9 to - 0.1, P = 0.039). There were no differences between both groups for short-term adverse outcomes and oncologic clearance. Overall survival (HR = 0.84, 95% CI 0.28 to 2.51, P = 0.761) and disease-free survival (HR = 0.57, 95% CI 0.20 to 1.64, P = 0.296) were comparable.

conclusionMIP is a safe and feasible approach for PNEN and is associated with a lower intraoperative blood loss, decreased postoperative stay and time to oral intake, at the expense of a longer operative time compared to OP.
