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

aimTo study the effects of daidzein on human pancreatic cancer cells in vitro.

methodsHuman estrogen-receptor (ER)-positive pancreatic cancer cells MiaPaCa-2 and ER-negative pancreatic cancer cells PANC-1 were treated by 0.1 micromol/L, 1 micromol/L, 10 microL, 25 microL, 50 microL, 75 microL and 100 microL of daidzein, respectively. Its antiproliferative effect was studied by MTT assay.

resultsDaidzein inhibited the growth of MiaPaCa-2 and PANC-1 cells at the concentrations from 0.1 microL to 100 microL. A dose- and time-dependent manner was found. The IC(50) of daidzein on MiaPaCa-2 and PANC-1 cells was 45 microL and 75 micro, respectively. After MiaPaCa-2 cells were treated by daidzein for 3 d and at the concentrations more than IC(50), the inhibitory manner was identical and the inhibition appeared a saturation phenomenon, but the inhibitory manner of daidzein on PANC-1 cells was different from that of MiaPaCa-2 cells.

conclusionDaidzein has antiproliferative effects on human estrogen-receptor-positive and negative pancreatic cancer cells, but their mechanisms may be different.
