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 current retrospective study aimed to assess the interaction between surgeon-volume and hospital-volume on outcomes after pancreatoduodenectomy (PD) for pancreatic ductal adenocarcinoma (PDAC).

methodsPatients with PDAC undergoing PD from 2008 to 2023 were identified using the National Cancer Database. Operative volumes of ≥20 cases/year defined high-volume hospitals (HVH) and ≥12 cases/year defined high-volume surgeons (HVS). Those below those thresholds were low-volume surgeons (LVS) and low-volume hospitals (LVH). Multivariable logistic regression was used to assess associations between surgeon/hospital volume and outcomes, relative to HVS/HVH.

resultsThe inclusion cohort consisted of 50,519 patients treated by 3155 surgeons operating at 976 hospitals. 90-day mortality declined with increasing volume: LVS/LVH = 6.4%, HVS/LVH = 5.7%, LVS/HVH = 4.0%, HVS/HVH = 3.5% (p < 0.001). Patients undergoing surgery by HVS/LVH [Odds Ratio (OR): 1.58, 95% Confidence Interval (95%CI) (1.12, 2.24), p = 0.009] and LVS/LVH [OR: 1.59, 95%CI (1.24, 2.04), p < 0.001] had a higher adjusted likelihood of mortality. LVS/HVH was not associated with mortality compared with HVS/HVH. Both HVS/LVH [OR: 1.93, 95%CI (1.27, 2.92), p = 0.002] and LVS/LVH [OR: 1.60, 95% CI (1.15, 2.23), p = 0.006] had a higher likelihood of readmission.

conclusionOutcomes after PD for PDAC remain more greatly influenced by hospital-volume rather than surgeon-volume.
