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

purposeWe evaluated the effects of combined treatment with the antiestrogen agent toremifene (TOR) and local hyperthermia (LHT) on the MCF-7 breast cancer cell line.

methodsBALB/c mice implanted with MCF-7 cells were divided into six treatment groups: a control group, a TOR30 group (given 30 mg/kg/day), a TOR120 group (given 120 mg/kg/day), an LHT group (43.5 degrees C), a TOR30 + LHT group, and a TOR120 + LHT group. The effects of the treatments on tumor cells, estrogen receptor (ER) expression, and cell cycle kinetics were measured after 21 days. We calculated the apoptotic index and vascular density inside the tumors and evaluated the efficacy of the transmigration of TOR into the tumors.

resultsThe antitumor effects were significantly greater in both combined therapy groups than in any of the single therapy groups. Estrogen receptor expression was weaker in the combined therapy groups than in the single therapy groups, and there were more G0/G1-phase cells and fewer S-phase cells in both combined therapy groups than in the single therapy groups. The apoptotic index was increased and the tumor vascular density was decreased in the combined therapy groups.

conclusionsWe attributed the effects of this combined therapy to the induction of apoptosis, the decrease in vascular density, and the increase and decrease in G0/G1-phase and S-phase cells, respectively, in the tumors.
