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

backgroundThe optimal stent type in patients receiving preoperative neoadjuvant chemoradiotherapy (NACRT) is uncertain. The present study aimed to compare the clinical effectiveness of biliary metallic stent (MS) and plastic stent (PS) in patients undergoing preoperative NACRT for resectable pancreatic cancer.

methodsThis retrospective study included 43 patients who required either biliary MS or PS before initiating NACRT for resectable or borderline resectable pancreatic head cancer. Seventeen patients had MS (MS group), while 23 patients had PS (PS group). All patients received preoperative NACRT, including gemcitabine and concomitant three-dimensional radiation of 54 Gy, and underwent pancreatectomy. Stent patency, surgery postponement, postoperative outcomes, and cost-effectiveness were compared between these groups.

resultsThere were no significant differences in baseline demographic or tumor characteristics between the groups. Stent patency was significantly longer in the MS group than in the PS group (p = 0.042). There were no differences in time to surgery, intraoperative characteristics, surgical complications, margin positivity, and pathological response between the groups. Furthermore, the medical cost of maintenance of biliary drainage during NACRT was similar between the groups.

conclusionsMS placement compared to PS in patients receiving preoperative NACRT provided no significant benefits during the postoperative course of pancreatectomy. However, MS placement was associated with long stent patency while showing no economic disadvantage. Therefore, MS placement may be recommended in patients receiving preoperative NACRT for resectable pancreatic cancer.
