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

purposeRadical antegrade modular pancreatosplenectomy (RAMPS) has been reported to achieve high rates of a negative margin and resected metastatic lymph nodes. However, many studies have used historical controls and the results remain controversial. We conducted this study to compare the surgical and long-term outcomes of RAMPS vs. conventional distal pancreatectomy (DP).

methodsThe subjects of this multicenter retrospective study were 106 patients who underwent curative resection for left-sided pancreatic cancer between 2012 and 2017. Overall survival (OS) and recurrence-free survival (RFS) rates were compared using Kaplan-Meier estimates.

resultsThe RAMPS group had more advanced T (T3/T4) and N stages (N1/N2) and a larger tumor size than the conventional group (T stage, p = 0.04; N stage, p = 0.02; tumor size, p = 0.04). The RAMPS group had more harvested metastatic lymph nodes (p = 0.02). After propensity-score matching, 37 patients from each group were included in the final analysis. There was no significant difference in RFS (p = 0.463) or OS (p = 0.383) between the groups. Multivariate analyses revealed the completion of chemotherapy to be an independent factor for RFS and OS (both p < 0.001).

conclusionsThere was no difference in the RFS or OS between RAMPS and conventional DP in this series. RAMPS may be an option for R0 resection of advanced tumors; however, postoperative chemotherapy has a greater influence than the surgical procedure on the prognosis of patients with pancreatic cancer.
