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

introductionSeveral Fistula Risk Scores (FRS) have been developed to predict postoperative pancreatic fistula (POPF) after pancreatoduodenectomy (PD). This study aimed to externally assess and compare the performance of the original (o-FRS), alternative (a-FRS), updated alternative (ua-FRS), and auditing (Aud-FRS) scores in a Southeast Asian cohort undergoing open and minimally invasive PD (MIS-PD).

methodsA post hoc analysis of a prospectively maintained database was performed including 724 consecutive patients who underwent PD (621 open, 103 MIS-PD) between 2005 and 2022 at a single tertiary institution. POPF was defined according to the 2016 ISGPS criteria (Grade B/C). Receiver operating characteristic analyses were used to assess predictive performance of each FRS. Associations between clinicopathologic variables and POPF were evaluated using logistic regression.

resultsThe overall area under the curve (AUC) for o-FRS, a-FRS, ua-FRS, and Aud-FRS were 0.675, 0.668, 0.672, and 0.662, respectively, indicating modest discrimination. Similar performance was observed across open and MIS-PD subgroups. Higher risk categories in ua-FRS and Aud-FRS were associated with increasing POPF incidence (p < 0.01). On multivariable analysis, smaller pancreatic duct diameter (OR 0.742, 95% CI 0.563-0.978) and pancreatojejunostomy compared with pancreatogastrostomy (OR 2.170, 95% CI 1.490-3.160) were independent predictors of POPF.

conclusionAll four FRS demonstrated consistent directional risk stratification but only modest discriminative ability in this Southeast Asian cohort. These findings suggest limited clinical utility without recalibration and highlight the need for population-specific refinement and objective pre-operative risk prediction models.
