Impact of Preoperative Factors of Dialysis Patients Who Underwent Pancreaticoduodenectomy on Postoperative Complications, 30-Day and Operative Mortality: Analysis Using the Japanese National Clinical Database.
Article in Journal of hepato-biliary-pancreatic sciences, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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.
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
backgroundPancreaticoduodenectomy (PD) in dialysis patients is rare but carries a high risk of complications and mortality. This study aimed to identify preoperative factors associated with severe postoperative complications and mortality.
methodsUsing the Japanese National Clinical Database, 329 dialysis patients undergoing PD between 2016 and 2020 were retrospectively analyzed. Multivariable penalized logistic regression identified preoperative risk factors for Clavien-Dindo classification (CDC) grade ≥ 4 complications, 30-day mortality, operative mortality, postoperative sepsis, and postoperative pancreatic fistula (POPF) (grade B or C).
resultsCDC grade ≥ 4 complications, 30-day mortality, and operative mortality occurred in 10.3%, 5.5%, and 11.2%, respectively. Diet- or oral medication-treated diabetes (Odds ratio 5.19, 95% confidence interval 1.19-22.66) and insulin-treated diabetes (7.50, 1.61-34.93) independently predicted 30-day mortality. Serum albumin levels < 3.0 g/dL independently predicted operative mortality (2.72, 1.05-7.02), while cardiovascular disease showed a borderline association (2.15, 0.95-4.85). Elevated CRP was significantly associated with postoperative sepsis (2.47, 1.07-5.67), and pancreatic cancer was associated with a lower risk of POPF (grade B or C) (0.59, 0.37-0.94).
conclusionsDialysis patients undergoing PD face perioperative risks. Early mortality is driven by acute metabolic and infectious vulnerability, whereas operative mortality reflects diminished physiologic reserve related to malnutrition and cardiovascular comorbidity.
