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

backgroundBetter pre-operative risk stratification may improve patient selection for pancreatic resection in pancreatic cancer. C-reactive protein (CRP) and the neutrophil-lymphocyte ratio (NLR) have demonstrated prognostic value in some cancers. The role of CRP and NLR in predicting outcome in pancreatic cancer after curative resection is not well established.

methodsAn electronic search of MEDLINE, EMBASE and CINAHL was performed to identify studies assessing survival in patients after pancreatic cancer resection with high or low pre-operative CRP or NLR. Systematic review was undertaken using the PRISMA protocol.

resultsIn total, 327 studies were identified with 10 reporting on survival outcomes after a pancreatic resection in patients with high or low CRP, NLR or both. All but one paper showed a trend of lower inflammatory markers in patients with longer survival. Three studies from six showed low CRP to be independently associated with increased survival and two studies of eight showed the same for NLR. All studies were retrospective cohort studies of low to moderate quality. DISCUSSION: Inflammatory markers might prove useful guides to the management of resectable pancreatic cancer but, given the poor quality of evidence, further longitudinal studies are required before incorporating pre-operative inflammatory markers into clinical decision making.
