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

backgroundObesity is associated with many adverse effects on female fertility. Obese women have a higher likelihood of developing ovulatory dysfunction due to dysregulation of the hypothalamic-pituitary-ovarian axis. However, the effect of obesity on ovarian function during early pregnancy needs to be further assessed.

methodsC57BL6/J mice were given a high-fat diet (HFD) for 12 weeks to induce obesity. An

resultsThe results of this study showed that during early pregnancy, the number of corpus lutea, serum estradiol and progesterone levels, and the expression of the steroid biosynthesis-related protein CYP19A1 (aromatase), CYP11A1 (cholesterol side chain cleavage enzyme), and StAR (steroidogenic acute regulatory protein), were significantly increased in HFD mice. Mice fed an HFD also showed a significant increase in ovarian lipid accumulation on day 7 of pregnancy. Genes involved in fatty acid synthesis (

conclusionsDuring early pregnancy, HFD-induced obesity increases fatty acid β-oxidation, which in turn increases TCA cycle and ETC related gene expression, leading to increased ATP production and ovarian dysfunction.
