The impact of age and comorbidity on localized pancreatic cancer outcomes: A US retrospective cohort analysis with implications for surgical centralization.
Article in Surgery open science, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers, 1 of them a synthesis that pooled 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.
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
Introduction: Age and comorbidity are independently associated with worse outcomes for pancreatic adenocarcinoma (PDAC). However, the effect of combined age and comorbidity on PDAC outcomes has rarely been studied. This study assessed the impact of age and comorbidity (CACI) and surgical center volume on PDAC 90-day and overall survival (OS). Methods: This retrospective cohort study used the National Cancer Database from 2004 to 2016 to evaluate resected stage I/II PDAC patients. The predictor variable, CACI, combined the Charlson/Deyo comorbidity score with additional points for each decade lived ≥50 years. The outcomes were 90-day mortality and OS. Results: The cohort included 29,571 patients. Ninety-day mortality ranged from 2 % for CACI 0 to 13 % for CACI 6+ patients. There was a negligible difference (1 %) in 90-day mortality between high- and low-volume hospitals for CACI 0-2 patients; however, there was greater difference for CACI 3-5 (5 % vs. 9 %) and CACI 6+ (8 % vs. 15 %). The overall survival for CACI 0-2, 3-5, and 6+ cohorts was 24.1, 19.8, and 16.2 months, respectively. Adjusted overall survival showed a 2.7 and 3.1 month survival benefit for care at high-volume vs. low-volume hospitals for CACI 0-2 and 3-5, respectively. However, there was no OS volume benefit for CACI 6+ patients. Conclusions: Combined age and comorbidity are associated with short- and long-term survival for resected PDAC patients. A protective effect of higher-volume care was more impactful for 90-day mortality for patients with a CACI above 3. A centralization policy based on volume may have greater benefit for older, sicker patients. Key message: Combined comorbidity and age are strongly associated with 90-day mortality and overall survival for resected pancreatic cancer patients. When assessing the impact of age and comorbidity on resected pancreatic adenocarcinoma outcomes, 90-day mortality was 7 % higher (8 % vs. 15 %) for older, sicker patients treated at high-volume vs. low-volume centers but only 1 % (3 % vs. 4 %) for younger, healthier patients.
