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

backgroundPancreatic cancer accounts for approximately 7% of all cancer deaths. More than half of all pancreatic cancers are stage IV at diagnosis, where systemic chemotherapy is used with the goal of life prolongation as well as palliation. The patient characteristics and health system factors that drive the use of systemic therapy are unknown.

methodThis is a retrospective study of stage IV pancreatic cancer patients (n = 140,210) diagnosed between 2000 and 2011 in the NCDB. NCDB contains approximately 70% of new cancer diagnosis from more than 1500 accredited cancer programs in the United States and Puerto Rico. Chi-squared test was used to determine any differences in characteristics of patients who did or did not receive systemic therapy.

resultsOur study demonstrated that only 49.1% of stage IV pancreatic cancer patients received systemic therapy. The use of systemic therapy is significantly lower in female, African American/Hispanic, patients older than 40 years, those without insurance or with Medicare and Medicaid, higher Charlson Comorbidity Score, poor economic and educational status and in nonacademic centers.

conclusionsThis is the largest study to evaluate the determinants of systemic therapy use in stage IV pancreatic cancer. The use of systemic therapy was significantly lower in patients older than 40 years, lower educational status, nonprivate insurance and with higher Charlson Comorbidity Scores. In addition, the use of systemic therapy was lower with female sex, African Americans/Hispanic, and lower socio-economic status. Understanding the barriers in the use of systemic therapy as well as appropriate utilization of systemic therapy can both optimize cancer care.
