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

purposeThe therapeutic strategy for borderline resectable pancreatic ductal adenocarcinoma (BR-PDAC) has remained unestablished because the preoperative prognostic factors have not been determined.

methodsOne hundred eighty-four consecutive PDAC patients who underwent upfront surgery with a curative resection between January 2000 and June 2013 at Kobe University Hospital were retrospectively studied. The PDAC patients were stratified into resectable (R)-PDAC (n = 147) and BR-PDAC patients (n = 37). We evaluated the independent prognostic significance of the neutrophil-lymphocyte ratio (NLR) and the platelet-lymphocyte ratio (PLR) in the BR-PDAC patients.

resultsBR-PDAC patient survival was significantly worse than R-PDAC patient survival (median survival time: 22.1 months vs. 24.3 months; 5-year survival rate 6 vs. 21 %; P = 0.042). The median survival in BR-PDAC patients with a preoperative NLR of >3 (n = 12) was 10.2 months, while that in patients with preoperative NLR of ≤3 (n = 25) was 24.9 months (P = 0.002). Moreover, the median survival in BR-PDAC patients with a preoperative PLR of >225 (n = 8) was 10.2 months, while that in patients with a preoperative PLR of ≤225 (n = 29) was 24.7 months (P = 0.003). Preoperative NLR >3 (HR = 2.980, 95 % CI 1.251-6.920; P = 0.015) and PLR >225 (HR = 3.050, 95 % CI 1.169-7.468; P = 0.024) were independent prognostic factors in BR-PDAC patients.

conclusionsHigher preoperative NLR and PLR can be independent predictive risk factors in BR-PDAC patients following curative resection.
