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

purposeDihydrotestosterone and testosterone are thought to be major contributors of prostate cancer progression and resistance. We studied the modulation of 15 circulating steroids by castration and their association with dihydrotestosterone and testosterone levels. MATERIALS

methodsA total of 116 serum samples were collected from 99 prostate cancer patients and categorized as eugonadal, castration-sensitive prostate cancer, castration-resistant prostate cancer, or castration-resistant prostate cancer under abiraterone acetate. Serum levels of 15 steroids were measured using mass spectrometry and compared between groups using analysis of variance. Intrapatient association of steroid levels and the androgens testosterone and dihydrotestosterone were assessed using Pearson correlation and linear regression.

resultsTestosterone, dihydrotestosterone, androstenedione, dehydroepiandrosterone, dehydroepiandrosterone-sulfate, androsterone, androstenediol, estrone, estrone-sulfate, estradiol, and androsterone/3α-diol-3/3α-diol-17-glucuronide levels were significantly decreased in castration-sensitive prostate cancer (castrated) compared to eugonadal patients. Testosterone levels were strongly associated with multiple steroids under eugonadal conditions, whereas they were weakly affected by precursor steroids in castrated patients. By contrast, dihydrotestosterone levels under androgen deprivation therapy were associated with testosterone and the backdoor pathway metabolite androsterone. In castration-resistant prostate cancer patients, levels of androstenedione were significantly associated with testosterone level, while testosterone was the only steroid associated with dihydrotestosterone levels.

conclusionsAndrogen deprivation therapy significantly reduces the levels of 13 circulating steroids. Upon androgen deprivation therapy initiation, the backdoor pathway metabolite androsterone are strongly associated with dihydrotestosterone levels. Under castration-resistant prostate cancer conditions, androstenedione was significantly associated with testosterone levels, suggesting the presence of tumor-related circulating androgens in these patients. These results provide further rationale to intensify treatments with androgen receptor axis signaling pathway inhibitors in patients with prostate cancer.
