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.
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
Recent studies have suggested that progestins play a role in the etiology of breast cancer; however, the mechanisms by which progestins promote tumor formation/progression have not been defined. Progestin action, in target tissues such as the breast, is mediated by the progesterone receptor (PR). PR signaling is complex and PR regulates transcription of target genes through a variety of mechanisms. Many cell signaling pathways are activated inappropriately in breast cancer cells and these pathways can regulate PR activity. For example, the p42/p44 MAPK pathway can regulate PR function by altering phosphorylation of PR, as well as its coregulators. We found that inhibition of the p42/p44 MAPK signaling pathway with a MEK inhibitor (U0126) impairs PR-mediated gene induction, but not gene repression. In addition, the effects of U0126 on PR-mediated gene transcription are much greater with long-term versus short-term inhibition and are gene-specific. Finally, treatment with U0126 delays phosphorylation of Ser294, but does not block phosphorylation completely, suggesting that p42/p44 MAPK kinase is not the dominant kinase responsible for phosphorylating this site. Collectively, these studies suggest that in addition to the p42/p44 MAPK pathway, other signaling pathways are also important for PR transcriptional activity in breast cancer cells. The integration of PR transcriptional effects and cell signaling pathways has implications for the initiation or progression of breast cancer. Understanding how these pathways interact may aid in the development of prevention and/or treatment strategies for the disease.
