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

BACKGROUND/

aimCurcumin is a natural compound of turmeric, which inhibits prostate cancer cell proliferation. This study examined whether treatment of LNCaP prostate cancer cells with the combination of curcumin and dutasteride, a 5-alpha reductase inhibitor, affect proliferation and the amount of testosterone and dihydrotestosterone. MATERIALS AND

methodsLNCaP Cells were incubated with curcumin or the combination of curcumin and dutasteride and cell proliferation was measured at 72 h. LC-MS/MS was used to determine testosterone and dihydrotestosterone concentrations in prostate cancer cells.

resultsCurcumin combined with dutasteride suppressed proliferation and affected apoptosis of LNCaP cells. The combination of curcumin and dutasteride also reduced the amount of testosterone and dihydrotestosterone in LNCaP cells. The secretion of prostate-specific antigen was inhibited by the combination treatment in a dose-dependent manner.

conclusionTreatment with the combination of curcumin and dutasteride may interfere with the intra-tumoral androgen activity.
