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

objectiveIn this study, the expression and clinical significance of vascular endothelial growth factor (VEGF), hypoxia inducible factor-1α (HIF-1α), and matrix metalloproteinase-2 (MMP2) in the placental villi of patients experiencing recurrent spontaneous abortion were investigated.

methodsFifty-one patients with recurrent spontaneous abortion (RSA) and 50 control individuals were enrolled (between January 2022 and December 2023). The messenger RNA (mRNA) and protein levels of VEGF, HIF-1α, and MMP2 in the placental villi of all enrolled patients were assessed using quantitative real-time polymerase chain reaction and western blot techniques. Additionally, the correlation between VEGF, HIF-1α, and MMP2 expression was analyzed using Pearson correlation coefficient.

resultsThe results revealed that the levels of VEGF mRNA and protein in the placental villi of patients with RSA were significantly lower than those in the control group, and this difference was statistically significant. Conversely, the mRNA and protein levels of HIF-1α and MMP2 were significantly higher in the RSA patient group than in the control group. Furthermore, the study revealed a negative correlation between the expression of VEGF and MMP2 in the placental villi of patients with RSA, and a positive correlation was observed between the expression of HIF-1α and MMP2.

conclusionThe downregulated expression of VEGF and upregulated expression of HIF-1α and MMP2 in the placental villi of patients with RSA may contribute to the pathogenesis of RSA. However, further investigation is required to elucidate the specific molecular regulatory mechanisms.
