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

backgroundWe sought to examine the impact of neoadjuvant chemotherapy (NCT), single agent or multiagent chemotherapy, and neoadjuvant chemoradiation (NCRT) on survival in pancreatic cancer.

methodsUtilizing the National Cancer Database, we identified patients who underwent pancreatic resection for adenocarcinoma (2006 to 2013). Overall survival (OS) analysis was performed using the Kaplan-Meier method. Multivariable cox proportional hazard models (MVA) and propensity score matching (PSM) were developed to identify predictors of survival. For upfront surgery (UFS), OS was limited to receipt of adjuvant treatment.

resultsWe identified 26,563 patients who underwent pancreatic resection: UFS =23,877, NCRT =1,482, and NCT =1,204. Multiagent chemotherapy was utilized in 77% of NCT and 42% of NCRT. There was improved R0 resections associated with neoadjuvant therapy compared to UFS, however, there was no difference between NCT and NCRT. In addition, the was improved R0 with MA-NCT (P<0.001) but not for single agent NCT (P=0.26). After PSM, the median OS for UFS, SA-NCT, MA-NCT, SA-NCRT, and MA-NCRT was 21.9, 21.5, 29.8, 25.3, and 25.8 months in all patients (P=0.001), and 23.6, 23.9, 31.6, 25.9, and 26.6 months in R0 patients (P=0.03), respectively. There was no difference in OS in patients with R1/2 resection. MVA after PSM demonstrated that only MA-NCT was associated with decreased mortality while increasing age, higher Charlson-Deyo index, N1, higher grade, tumor size, and positive margins were associated with higher mortality.

conclusionsThere was improved OS associated with MA-NCT in pancreatic cancer patients compared to UFS with adjuvant therapy.
