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

backgroundThe aim of our study was to compare the outcomes of periampullary and extra-ampullary duodenal adenocarcinomas and segmental duodenal resection versus pancreatoduodenectomy and to evaluate prognostic factors.

methodsWe performed a retrospective review of all adults treated for duodenal adenocarcinoma by operative resection at a large tertiary referral center from 1994 to 2009.

resultsOne hundred twenty-four patients had an operation for duodenal adenocarcinoma over a 15-year period (periampullary, n = 25, and extra-ampullary, n = 99). Ninety-nine patients (80%) underwent curative resection, including 24 (96%) with periampullary and 75 (76%) with extra-ampullary carcinomas. The average number of lymph nodes sampled was eight with segmental resection and 12 with pancreatoduodenectomy (p < 0.001). Five-year overall survivals were 37% for the entire cohort (n = 124), 37% in the extra-ampullary group, and 38% in the periampullary group. Tumor size (p = 0.20), positive nodes (p = 0.60), segmental resection versus pancreatoduodenectomy (p = 0.55), adjuvant therapy (p = 0.23), and R(1) versus R(0) resection (p = 0.21) were not associated with survival. In contrast, advanced T stage and pathologic grade were associated with poor survival.

conclusionExtra-ampullary and periampullary duodenal adenocarcinomas have similar survival after resection. For distal duodenal tumors, survival is improved by curative resection without being compromised by limited resection. The number of lymph nodes sampled was significantly less with segmental resection than pancreatoduodenectomy.
