Real-world patterns of adjuvant chemotherapy treatment for patients with resected pancreatic adenocarcinoma.

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
The aim of the study was to analyze the real-world treatment patterns of adjuvant chemotherapy administration among patients with resected pancreatic adenocarcinoma. Cases with non-metastatic pancreatic adenocarcinoma, diagnosed 2007-2018, treated with upfront surgical resection, and recorded within Alberta Cancer registry were accessed. Multivariable logistic regression analysis was conducted to evaluate factors predicting use of adjuvant chemotherapy. Kaplan-Meier survival estimates and multivariable Cox regression analysis were used to compare overall survival among patients treated with adjuvant gemcitabine versus those treated with adjuvant gemcitabine + capecitabine. A total of 695 patients who have undergone upfront surgical treatment of pancreatic adenocarcinoma, including 445 patients (64%) who received adjuvant chemotherapy and 250 patients (36%) who did not receive adjuvant chemotherapy. The following factors were associated with lower probability to receive adjuvant chemotherapy: older age (OR 0.94; 95% CI 0.93-0.96), node negativity (OR 0.47; 95% CI 0.33-0.67), higher Charlson comorbidity index (OR 0.86; 95% CI 0.74-0.99), and living within the Northern zone of the province (OR for Calgary zone versus North zone: 2.24; 95% CI 1.29-3.90). Within patients who received adjuvant gemcitabine ± capecitabine, factors associated with worse overall survival included higher Charlson comorbidity index (HR 1.18; 95% CI 1.00-1.40), and node-positive disease (HR for node-negative versus node-positive disease: 0.51; 95% CI 0.33-0.78). Type of chemotherapy was not predictive of overall survival (HR for gemcitabine versus gemcitabine plus capecitabine: 1.40; 95% CI 0.98-2.00). P value for interaction between type of chemotherapy and nodal status was 0.038. In this real-world study, the added benefit of adjuvant gemcitabine + capecitabine (compared to adjuvant gemcitabine) seems to be limited to patients with node-positive disease.
