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

purposeObservational data suggest that women conceiving without a corpus luteum are at higher risk of developing preeclampsia. While the underlying mechanisms remain unclear, the absence of corpus luteum-derived secretory products may be a contributing factor. This study investigates whether the plasma proteome differs between women who conceive with or without a corpus luteum and examines the relationship with mode of conception.

methodsPlasma samples from 12 participants were collected at three time points: first trimester, third trimester, and postpartum. The cohort included women who conceived unassisted (UC) after infertility, via artificial cycle frozen embryo transfer (AC FET), or natural cycle frozen embryo transfer (NC FET). A total of 36 plasma protein samples were analyzed using mass spectrometry-based proteomics to compare the proteome of women who conceived with and without a corpus luteum, across different conception methods and pregnancy stages.

resultsIn total, 528 proteins were quantified. No differentially expressed plasma proteins were identified between women with and without a corpus luteum. However, 15 proteins showed differential expression between UC and FET at all time points, with Bonferroni-corrected p < 9.47 × 10

conclusionThis pilot study revealed a unique proteomic signature associated with the mode of conception. The findings suggest biologically plausible candidate proteins for further testing. Validation in larger cohorts or with alternative proteome analysis technologies is needed.
