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

The aim is to study the association of estrogen receptor α (ERα) and estrogen receptor β (ERβ) gene polymorphisms and diplotypes with ovarian response to follicle-stimulating hormone (FSH) stimulation and the hormone levels [FSH, luteinizing hormone (LH), E2] at the third day of the menstrual cycle. Three hundred women undergoing medically assisted reproduction and 300 women with at least one spontaneous pregnancy participated in the study. ERα PvuII and XbaI polymorphisms as well as ERβ AluI polymorphism were genotyped. The FSH, LH, and E2 levels were determined at the third day of the menstrual cycle, while the follicular size, the follicle, and oocyte numbers were recorded during oocyte retrieval. PvuII CC, XbaI GG, and AluI GG women were characterized by increased amounts of large follicles compared to PvuII TT, XbaI AA, and AluI AA women (p = 0.045, 0.01, and 0.033, respectively). The PvuII CC/XbaI GG diplotype was also significantly associated with higher large follicle numbers compared to the PvuII TT/XbaI AA diplotype (p = 0.024). However, no associations were observed between ER gene polymorphisms and the hormonal profile, the follicle/oocyte numbers, and the pregnancy rates. ERα and ERβ genetic variants were associated with ovarian response to standard gonadotropin stimulation of women undergoing in-vitro fertilization affecting mainly the follicular growth.
