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

objectiveTubal ectopic pregnancy (TEP) remains the most common cause of maternal morbidity and mortality in the early months of pregnancy. The aim of this study is to perform the correlation between PROKRs and pro-inflammatory genes and explore the role of novel genes in pathogenesis of TEP.

methodsHere, quantitative real time PCR and immunohistochemistry were used to assess the expression of the novel genes in 120 TEP patients and 30 age-matched non-TEP patients. The correlation between PROKRs and pro-inflammatory genes were analyzed by Pearson correlation coefficient. Univariate and multivariate Cox regression analyses were used to assess the risk prediction rate of novel genes. Receiver operating characteristic was used to assess the performance of our model.

resultsPROKRs (PROKR1 and PROKR2) and pro-inflammatory genes (TNF-α, IL-6, and IL-8) expression levels significantly enhanced in TEP patients, and significantly positive correlation with pro-inflammatory genes for PROKRs. A multivariate Cox regression analysis demonstrated that 2 genes (PROKR2 and IL8) had significant diagnostic value, which were associated with the occurrence and development of TEP.

conclusionOur data further denote that dysregulation of PROKR2 and IL-8 were risk factor and played an important role in the pathogenesis of TEP.
