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

Oestradiol-17beta (Oe(2)) stimulates uterine epithelial cell proliferation and is critical for normal uterine differentiation and secretory function. Oe(2) can act directly on the epithelium via the epithelial oestrogen receptor (OR) or indirectly via the OR-positive underlying stroma. A primary role for epithelial-stromal interactions has been established for mediating steroid hormone action in the uterus. This study was undertaken to determine the mode of Oe(2) action in regulating epithelial cell cytokine release in the uterus. Mouse uterine epithelial and stromal cells were isolated and cultured separately. Transepithelial resistance (TER) was monitored with an EVOM voltohmmeter to determine monolayer polarity and integrity. Epithelial cells grown alone or in coculture with stromal cells were treated with Oe(2). Supernatants collected were assayed for transforming growth factor-beta (TGF-beta) and tumour necrosis factor-alpha (TNF-alpha) by bioassay and enzyme-linked immunosorbent assay, respectively. While Oe(2) treatment of epithelial cells led to a significant decrease in TER, the amount of TNF-alpha released was not altered. However, when epithelial cells were cocultured with stromal cells and treated with Oe(2), apical TNF-alpha release was significantly decreased, compared to cells not treated with hormone. As determined by oestrogen receptor antagonist studies, Oe(2) primed epithelial cells for the action of the stromal paracrine factor(s). In contrast, TGF-beta release by epithelial cells was not affected by Oe(2) when grown alone or in the presence of stromal cells. These studies indicate that Oe(2) has both direct and indirect effects on the uterine epithelium. While epithelial monolayer integrity is directly influenced by Oe(2), TNF-alpha release in response to Oe(2) is dependent on the presence of stromal cells, indicating that paracrine communication is necessary for steroid regulation of some but not all cytokines.
