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

BACKGROUND AND

aimMetal (MS) or plastic stents (PS) are placed for preoperative biliary drainage (PBD) in patients with pancreatic ductal adenocarcinoma (PDAC) undergoing neoadjuvant chemotherapy (NAC) or chemoradiotherapy (NACRT). This multicentre retrospective study compared the safety and efficacy of PBD using MS and PS, including surgery-related adverse events (AEs) and other clinical outcomes.

methodsThis study enrolled patients with resectable or borderline resectable PDAC requiring NAC or NACRT who underwent PBD with MS or PS at 17 tertiary care hospitals in Japan between January 2016 and December 2021. Clinical outcomes were retrospectively analysed.

resultsOf the 249 patients who underwent pancreatectomy, 121 underwent PBD with MS and 128 with PS. Because there were significant differences in baseline characteristics between these groups, propensity score matching was performed, resulting in 66 matched pairs. The RBO rate was significantly lower (15.2% vs. 56.1%, p < 0.001); the time to surgery (p = 0.027) and postoperative hospital stay (p = 0.036) were significantly shorter in the MS group. The incidence of postoperative AEs was significantly lower in the MS group (18.2% vs. 34.9%, p = 0.030) than in the PS group. Univariate and multivariate analyses identified the placement of an MS for PBD as an independent protective factor for postoperative AEs (odds rates: 0.35, p = 0.017).

conclusionIn patients with PDAC undergoing NAC or NACRT, MS placement for PBD was associated with lower rates of postoperative AEs and RBO than PS placement. MS is a more suitable option than PS for PBD.
