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

backgroundThe omega-3 (ω-3) fatty acid eicosapentaenoic acid (EPA) is currently used in the clinic as a nutritional supplement to improve infertility, particularly in women with polycystic ovarian syndrome (PCOS).

objectiveThe present study was designed to investigate the effect of EPA on insulin-like growth factor 1 (IGF-1) and cyclooxygenase 2 (COX-2) gene expression in primary cultured granulosa cells from patients undergoing in vitro fertilization (IVF), and also to compare this effect with those in granulosa cells of PCOS patients. MATERIALS AND

methodsIn this experimental study, human granulosa cells were isolated from follicular fluid of normal and PCOS women undergoing IVF by hyaluronidase digestions, followed by Percoll gradient centrifugation. Cells were cultured in vitro, exposed to a range of concentrations of the EPA (25-100 µM) for 24 hr, and investigated with respect to COX-2 and IGF-1 gene expression by real time-PCR.

resultsIn both groups, all doses of the EPA significantly induced IGF-1 mRNA gene expression compared to the untreated control. High doses of EPA in the presence of recombinant (r) FSH produced a stimulatory effect on IGF-1 and a suppressive effect (p=0.01) on the COX-2 gene expression, which were more pronounced in granulosa cells from PCOS patients.

conclusionEPA affect diversely the gene expression of IGF-1 and COX-2 in granulosa cells, which were more pronounced in PCOS compared to control. These findings represent the possible underlying molecular mechanisms for the positive impact of the ω-3 fatty acids on reproduction, especially in patients with PCOS.
