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

backgroundEndothelins (EDNs) are thought to modulate endometrial blood flow during menses, stromal healing and endometrial growth during the proliferative phase. Our goal was to assess the effects of estrogen and progesterone on the EDN paracrine system in the endometrium of rhesus macaques.

methodsIn this study, archived samples were used. These samples were collected from oophorectomized rhesus macaques that were treated sequentially with estradiol (E(2)) and then E(2) plus progesterone to create artificial menstrual cycles. Endometrium from animals in the menstrual, proliferative and secretory phases of the artificial cycle were analyzed by real-time PCR, in situ hybridization and immunocytochemistry to detect changes in EDN peptides (EDN1, EDN2, EDN3), EDN receptors (EDNRA, EDNRB), EDN-converting enzyme 1 (ECE1) and membrane metalloendopeptidase (MME)-an enzyme that degrades the EDNs.

resultsCompared with the late secretory phase, progesterone withdrawal at the end of the artificial menstrual cycle triggered an increase (P< 0.05) in EDN1, EDNRB and ECE1 in the upper functionalis zone during menses of the next cycle. Treatment with E(2) alone in the proliferative phase increased (P< 0.05) EDNRA transcript, which was confined predominantly to the stromal cells. E(2) plus progesterone in the artificial secretory phase suppressed (P< 0.05) the expression of EDN3 in the functionalis zone stroma and epithelia, tended (P= 0.08) to attenuate levels of epithelial EDN2 and markedly up-regulated (P< 0.05) the stromal expression of MME.

conclusionsOur results indicate that estrogen and progesterone regulate the EDN family during the menstrual cycle. The changes in the EDN paracrine system during the mid-secretory phase may indicate a role for EDN during embryo implantation.
