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

backgroundIn the consideration of ampullary adenocarcinoma, T stage, lymph node metastases, perineural invasion, tumor differentiation, pancraticobiliary type, and lymph node ratio are considered prognostic factors. The objectives of this study were to investigate surgical outcomes and the clinicopathological predictors affecting survival and recurrence, and to examine the prognostic roles of histopathological subtype and immunohistochemical markers.

methodsFrom April 2006 to September 2012, 37 patients who underwent curative resection of ampullar of Vater adenocarcinoma were enrolled in this study. A retrospective review was performed based on medical records. Immunohistochemical expression, histopathological type and clinicopathologic factors were analyzed.

resultsThe 5-year overall survival rates and disease-free survival rates after surgery were 77.4 and 75.7 %, respectively. Multivariate Cox regression analysis showed that advanced T stage (p = 0.019) and positive expression of Cytokeratin 7 (CK7) with negative expression of Cytokeratin 20 (CK20) (p = 0.046) were identified as significant independent factors related to survival, and poor differentiation (p = 0.031) significantly influenced disease-free survival in multivariate analysis.

conclusionsAdvanced T stage is a significant prognostic factor affecting survival in ampullary adenocarcinoma. Also, positive expression of CK7 with negative expression of CK20 is an independent factor related to overall survival.
