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

backgroundSeveral recent studies provide evidence that D-dimer (DD) concentration in peripheral blood correlates negatively with overall survival (OS) in patients with pancreatic ductal adenocarcinoma (PDAC). Contrarily, there are recent evidence indicating that preoperative plasma fibrinogen, but not D-dimer might represent a prognostic factor in non-metastatic gastrointestinal cancers.

methodsIn a single-center prospective study, we enrolled 62 patients undergoing surgery for pathologically confirmed PDAC without detectable venous thrombosis. Intraoperatively, the sample of the blood from the portal vein was obtained. DD concentration in these samples was measured. Patients were followed postoperatively until time of death from any cause.

resultsWe found that OS for patients with portal blood DD values above 2700 (ng/mL) (n = 22 from 62 patients) was higher by 158% than that for the patients (n = 42) with DD values ≤ 2700 (416 days versus 161 days, p = 0.05). On the contrary to the studies investigating DD concentration in peripheral blood, we have found that patients with higher DD level in the portal vein had longer mean OS than patients with lower ones.

conclusionsFurther investigation is necessary both to confirm our results in a larger patient population and to elucidate the mechanism for the correlation between portal blood D-dimer concentrations and survival time. Along with other authors, we conclude that portal circulation is characterized by unique, biological environment that requires further evaluation.
