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

backgroundDespite the increasing use of neoadjuvant treatment, the question of whether preoperatively treated, successfully resected patients should receive additional postoperative adjuvant treatment remains unanswered. We evaluate the impact of adjuvant therapy following neoadjuvant treatment and pancreatectomy in pancreatic cancer patients in a large national study.

methodsWe used the National Cancer Data Base between 2006 and 2013 to identify resected, non-metastatic pancreatic adenocarcinoma patients who received neoadjuvant chemo(radio)therapy followed by pancreatectomy. Kaplan-Meier and multivariate Cox proportional hazard regression analyses were performed to compare survival between groups.

resultsIn total, 1357 patients were identified. Of the patients, 38.6% (n = 524) were treated with postoperative therapy. There was no difference in unadjusted median overall survival between patients who did and did not receive postoperative therapy (median survival, 27.5 vs. 27.1 months, log-rank p = 0.5409). Postoperative therapy was not significantly associated with favorable prognosis in patients with positive resection margins (log-rank p = 0.6452) or positive lymph nodes (log-rank p = 0.6252). On multivariate analysis, receipt of postoperative therapy was not predictive of survival (hazard ratio 0.972; 95% CI 0.848-1.115; p = 0.6876).

conclusionsOur results using national data suggest that after receipt of neoadjuvant therapy and pancreatectomy, additional postoperative therapy may not provide additional survival benefit. These data warrant further prospective data collection and consideration for clinical trials.
