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

backgroundProstate cancer in black men is associated with poorer outcomes than their white counterparts. However, most studies reporting this disparity were conducted in localized prostate cancer and primarily in the United States.

methodsData regarding prostate cancer incidence and mortality for East London between 2008 and 2010 were obtained from the UK National Disease Registration Service. We further evaluated survival outcomes of 425 cases of mCRPC in St Bartholomew's Hospital, East London, between 1997 and 2016, and analyzed whether ethnicity impacted on responses to different treatment types.

resultsThe incidence of prostate cancer in black men was higher than white men in East London. Prostate cancer-specific mortality was proportional to incidence based on ethnic groups. In the detailed analysis of 425 patients, 103 patients (24%) were black (B), and the remainder white (W). Baseline characteristics were comparable in both groups, although black patients had a lower baseline hemoglobin (p < 0.001). Median overall survival for the total cohort was 25.5 months (B) vs 21.8 months (W) (hazard ratio (HR) = 0.81, p = 0.08). There was prolonged survival in the black population in those who only received hormone-based treatment throughout their treatment course; 39.7 months (B) vs 17.1 months (W) (HR = 0.54, p = 0.019).

conclusionBlack men may do better than white men with mCRPC, in the context of equal access to healthcare. The study also suggests a greater margin of benefit of hormone-based therapy in the black subpopulation.
