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

purposeTo investigate the impact of postoperative complications on survival after curative resection for pancreatic cancer.

methodsWe reviewed retrospectively the medical records of 122 patients who underwent curative R0 resection for pancreatic cancer. Major complications included pancreatic fistula and hemorrhage of grade B or C according to the International Study Group of Pancreatic Fistula or Surgery criteria, and other complications of grade ≥III according to the Clavien-Dindo classification.

resultsThirty-eight patients (31 %) suffered major postoperative complications and 40 patients (33 %) suffered minor complications only. Univariate survival analysis showed that patients with major complications had a significantly worse prognosis than those without major complications, with regard to recurrence-free survival (RFS) (P < 0.01) and overall survival (OS) (P < 0.01), whereas minor complications did not affect survival. Major complications significantly inhibited or delayed adjuvant chemotherapy. Multivariate survival analysis showed that the absence of postoperative major complications was an independent favorable factor for RFS (hazard ratio 0.48; 95 % confidence interval: 0.28-0.85) and OS (hazard ratio 0.47; 95 % confidence interval 0.27-0.81).

conclusionsPostoperative major complications after pancreatectomy for pancreatic cancer affect the prognosis.
