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

objectiveWhile a certain fraction of endometriomas can develop de novo epithelial ovarian cancer (EOC) such as clear cell carcinoma (OCCC), there is currently no useful biomarker available for early detection of OCCC from endometriomas. The aim of this study was to describe the diagnostic utility of a novel biomarker for EOC especially for OCCC to distinguish from endometrioma.

methodsMore than 100,000 glycan structures of serum glycoproteins obtained from 134 pretreatment all stage EOC patients (including 45 OCCCs) and 159 non-cancer control women (including 36 endometriomas) were explored for a mass spectrum approach. Diagnostic accuracy of identified biomarker was compared to the one of CA-125 by comparing area under curve (AUC) and positive/negative predictive values (PPV and NPV).

resultsA2160, a fully-sialylated alpha-chain of complement 4-binding protein, was identified as a candidate target marker. A2160 was significantly elevated in all stages of OCCC compared to with endometriomas. Diagnostic accuracy of A2160 (cutoff 1.6U/mL) to distinguish early stage OCCC from endometrioma is significantly higher than that of CA-125 (cutoff 35IU/L): AUC for A2160 versus CA-125, 0.92 versus 0.67; PPV 95% versus 64%; and NPV 85% versus 58%. In addition, fully-sialylated glycans had a higher accuracy for diagnosing EOC as compared to partially-sialylated glycans of alpha-chain of complement 4-binding protein.

conclusionOur study suggested that A2160 may be a useful biomarker to distinguish early-stage OCCC from endometrioma. This new biomarker can be potentially applied for the monitoring of endometrioma patients, making possible the early diagnosis of OCCC.
