Platelets in preeclampsia: an observational study of indices associated with aspirin nonresponsiveness, activation and transcriptional landscape.
Observational study in BMC medicine, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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.
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
backgroundPlatelets play critical roles in the pathogenesis of preeclampsia, including thrombosis, endothelial dysfunction and inflammation. However, preeclampsia-associated changes in platelet gene expression and activation at the maternal-foetal interface remain unknown. Moreover, aspirin nonresponsiveness in high-risk pregnancies underscores the need for low-cost biomarkers to identify nonresponders. Nevertheless, the changes of platelet indices in women who develop preeclampsia despite aspirin prophylaxis have not yet been evaluated. In this study, we aimed to investigate the changes in platelet indices associated with aspirin nonresponsiveness, activation state and transcriptional landscape in preeclampsia.
methodsPlatelet indices were compared between aspirin-responsive and nonresponsive women. Logistic regression analysis was performed to determine the associations between platelet indices and aspirin nonresponsiveness. Opal immunofluorescence staining was performed to evaluate the expression of platelet-specific (CD42b) and activation (CD62P) markers in placental villous and decidual tissues. RNA sequencing (RNA-seq) was performed to investigate the transcriptomic profile of platelets.
resultsA decrease in platelet count (PC) during the second trimester as well as an increase in mean platelet volume (MPV) and a lower PC/MPV ratio in the third trimester were significantly associated with the subsequent development of aspirin nonresponsiveness. We observed significantly greater expression of CD62P in the placental villous and CD42b in the decidua of the preeclamptic group than in those of the nonpreeclamptic group. Colocalization analysis of CD42b and CD62P revealed that the preeclamptic placenta and decidua presented significant platelet activation. RNA-seq analysis revealed a total of 20, 618 and 1819 transcripts in the peripheral blood, placental villous and decidua of preeclamptic women, respectively. Functional analysis revealed that the PI3K-Akt and Wnt signalling pathways were significantly enriched in the placental villous and decidua of preeclamptic patients, respectively. RT‒qPCR analysis confirmed the upregulation of FKBP5, LAMA5, FZD5 and FGG mRNA expression in preeclampsia.
conclusionsOur findings suggest that PC in the second trimester and PC, MPV and PC/MPV ratio in the third trimester may be useful for assessing aspirin nonresponsiveness in women at high risk of preeclampsia. Furthermore, our findings demonstrate that preeclampsia is associated with increased platelet activation and significant enrichment of signalling pathways involved in platelet activation.
