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

backgroundAndrogens play an essential role in the development and differentiation of the prostate gland; their contribution to pathological conditions, such as benign prostatic hyperplasia and prostate cancer (PC), remains unclear.

aimWe reviewed relationships between androgens and the prostate both in physiological and pathological conditions. MATERIAL AND

methodsA systematic search of published evidence was performed using Medline (1969 to September 2010).

resultsAndrogen-dependency of prostate growth is evident only in the hypogonadal condition, but not in the eugonadal state (the "saturation hypothesis"). There is unequivocal evidence that reducing androgen signaling to the hypogonadal range can reduce PC growth and patient symptoms. At physiological testosterone concentration there is no link between androgen levels and PC risk. In addition, different strategies of androgen deprivation (ADT) for advanced PC are only palliative and rarely cure patients. Preliminary evidence indicates that a low androgen milieu is associated with tumor aggressiveness. Transition to androgen-independence is complex and involves both selection and outgrowth of preexisting androgen resistant clones, as well as adaptative upregulation of genes that help the cancer cells to survive and grow after ADT. Because androgens are essential for the regulation of fat distribution, insulin sensitivity, and lipid and bone metabolism, recent publications have highlighted the concept that ADT may also be involved with an increase in overall, as well as cardiovascular, morbidity and mortality.

conclusionsWhile ADT still represents a cornerstone for the palliative therapy of a small fraction of aggressive PC, a "misuse and/or abuse" of ADT should be avoided.
