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

objectiveSome studies have shown that the methylation status of the GSTP1 gene promoter is related to the incidence of prostate cancer, but this finding is still controversial. The aim of this study was to evaluate the association between glutathione-S-transferase p1 (GSTP1) promoter methylation and the incidence of prostate cancer.

methodsThe Medline, Embase, Web of Science, and Cochrane CENTRAL databases were searched from their inception to February 22, 2019. According to the inclusion criteria, studies of the association between the methylation status of the GSTP1 gene promoter and prostate cancer were included. The difference in the incidence of GSTP1 promoter methylation in tissues, blood, or urine between patients with prostate cancer and those without prostate cancer were compared, and the results were expressed as the odds ratio (OR) and 95% confidence interval (CI). The pooled OR of each study was estimated using a fixed-effects model or a random-effects model to generate forest plots.

resultsUltimately, 15 studies (1540 samples) were included. The estimated effect from our meta-analysis showed that the incidence of GSTP1 promoter methylation was higher in patients with prostate cancer than in those without prostate cancer (OR 18.58, 95% CI 9.60-35.95, P = 0.000). GSTP1 promoter methylation was highly correlated with the incidence of prostate cancer.

conclusionsMethylation of the GSTP1 promoter may increase the risk of prostate cancer. This study may provide a strategic direction for prostate cancer research. Pending validation of these findings, the methylation of the GSTP1 promoter may be a potential biomarker to diagnose prostate cancer.
