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

Hormone therapy is an effective approach for the treatment of breast cancer. Although the antiestrogen tamoxifen has had a major impact on the treatment of the disease, aromatase inhibitors (AIs), which reduce estrogen synthesis, have recently proved to be more effective. These agents are now used as first-line therapy for postmenopausal breast cancer. Nevertheless, despite the efficacy of these agents, resistance to treatment eventually may occur in some patients. In an effort to overcome this resistance and extend the benefits of AIs, investigators have studied the mechanisms involved in resistance to AIs. Adaptive changes that result in activation of alternate signaling pathways in AI-resistant tumors have been identified in xenograft and cell line models. Expression of estrogen receptor α and aromatase was shown to be decreased in tumors after long-term treatment with AIs. In contrast, increased expression was observed in tyrosine kinase receptors such as Her-2 and insulin-like growth factor receptor, as well as in downstream signaling proteins such as mitogen-activated protein kinase. Functional activation of the mitogen-activated protein kinase pathway and dependency on growth factor receptor signaling have been observed in AI-resistant cells and tumors.
