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

purposeThe optimal treatment for high-risk prostate cancer (Pca) remains to be established. We previously reported favorable biochemical recurrence-free survival (BRFS) for high-risk Pca patients treated with neoadjuvant therapy comprising a luteinizing hormone-releasing hormone agonist plus low-dose estramustine (LHRH + EMP) prior to radical prostatectomy (RP). In the present study, we evaluated the efficacy of neoadjuvant therapy comprising a gonadotropin-releasing hormone antagonist plus low-dose estramustine phosphate (GnRH + EMP) in patients with high-risk Pca.

methodsBetween September 2005 and March 2016, we identified 406 high-risk Pca patients of whom 136 received neoadjuvant GnRH + EMP (GnRH group) and 270 received LHRH + EMP (LHRH group) before RP. We retrospectively evaluated the clinical and pathological covariates between the two groups. The endpoint was the rate of pathological T0 status.

resultsThe rates of pathological T0 status were 11.0 and 8.9% in the GnRH group and LHRH group, respectively (P = 0.490). The 2-year BRFS rates were 97.8% in the GnRH group and 87.8% in the LHRH group (P = 0.027).

conclusionOur findings suggest that neoadjuvant GnRH antagonist + EMP followed by RP may improve the pathological outcomes and reduce the risk of biochemical recurrence in patients with high-risk Pca. Further prospective studies to confirm these findings are warranted.
