Nationwide Outcomes of Pancreaticoduodenectomy for Pancreatic Malignancies: Center Volume Matters.
Article in The American surgeon, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
backgroundComplex surgeries such as pancreaticoduodenectomies (PD) have been shown to have better outcomes when performed at high-volume centers (HVCs) compared to low-volume centers (LVCs). Few studies have compared these factors on a national level. The purpose of this study was to analyze nationwide outcomes for patients undergoing PD across hospital centers with different surgical volumes.
methodsThe Nationwide Readmissions Database (2010-2014) was queried for all patients who underwent open PD for pancreatic carcinoma. High-volume centers were defined as hospitals where 20 or more PDs were performed per year. Sociodemographic factors, readmission rates, and perioperative outcomes were compared before and after propensity score-matched analysis (PSMA) for 76 covariates including demographics, hospital factors, comorbidities, and additional diagnoses. Results were weighted for national estimates.
resultsA total of 19,810 patients were identified with age 66 ± 11 years. There were 6,840 (35%) cases performed at LVCs, and 12,970 (65%) at HVCs. Patient comorbidities were greater in the LVC cohort, and more PDs were performed at teaching hospitals in the HVC cohort. These discrepancies were controlled for with PSMA. Length of stay (LOS), mortality, invasive procedures, and perioperative complications were greater in LVCs when compared to HVCs before and after PSMA. Additionally, readmission rates at one year (38% vs 34%, P < .001) and readmission complications were greater in the LVC cohort.
conclusionsPancreaticoduodenectomy is more commonly performed at HVCs, which is associated with less complications and improved outcomes compared to LVCs.
