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

objectiveTo evaluate the effect of elevated plasma fibrinogen levels on the prognosis of epithelial ovarian cancer (EOC).

methodsWe reviewed the data of 217 patients with advanced-stage EOC between 2000 and 2012, and investigated the prognostic role of elevated plasma fibrinogen levels compared with serum CA-125 levels, neutrophil to lymphocyte ratio (NLR) and platelet to lymphocyte ratio (PLR). For further evaluation, we performed a meta-analysis using 5 cohort studies published to July 2015, including our cohort study after a literature review.

resultsAmong the four biomarkers, only plasma fibrinogen levels >485.2 mg/dL were correlated with impaired progression-free survival (PFS) and overall survival (OS) (median, 13.9 vs. 20.3 months and 42.2 vs. 55.4 months; p<0.010). Elevated plasma fibrinogen levels were an independent factor for poor PFS with marginal significance and OS (adjusted hazard ratios [HRs]=1.389 and 1.581; 95% confidence intervals [CIs]=0.979-1.972 and 1.032-2.423, respectively). Furthermore, crude and subgroup meta-analyses demonstrated that elevated plasma fibrinogen levels were associated with impaired PFS and OS in patients with all stage EOC.

conclusionElevated plasma fibrinogen levels be more important for predicting survival than serum CA-125 levels, NLR and PLR in patients with EOC, in particular, advanced-stage disease. Moreover, it may be related to poor prognosis of EOC.
