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
backgroundPreeclampsia (PE) is a severe pregnancy complication characterized by hypertension and proteinuria. PE poses a substantial threat to the health of both mothers and fetuses, and currently, there is no definitive treatment available. Recent studies have indicated that the transcription factor GATA1 may be implicated in the pathological processes of PE, but the underlying mechanism remains elusive. NTRK2/cGMP-PKG signaling pathway plays a crucial role in regulating the function and polarization of macrophages, which are key immune cells at the maternal-fetal interface. This study aims to investigate the role of GATA1 in the pathogenesis of PE, with a specific focus on how GATA1-regulated TrkB/cGMP-PKG signaling in macrophages and its dysregulation contribute to the development of preeclampsia.
methodsBy employing THP-1 cells, co-culture systems of THP-1 cells and HTR-8/Svneo, HPVECs and Sprague-Dawley (SD) rats, in conjunction with gene knockdown and overexpression techniques, we explored the effects of GATA1 on the TrkB/cGMP-PKG signaling pathway. Transcriptomic sequencing, bioinformatics analysis, animal experiments, and clinical sample collection were conducted to validate the role of GATA1 in PE.
resultsKnockdown of GATA1 mitigated the symptoms of PE, and this effect was reversed by overexpression of TrkB. In comparison with the control group, the proportion of M2 cells elevated significantly in the sh-GATA1 group (P < 0.001). In addition, the protein expressions levels of TrkB, cGMP, and PKG were significantly decreased in the sh-GATA1 group were significantly decreased compared with those in the control group (P < 0.001, P < 0.001, P < 0.001, P < 0.05, respectively). Moreover, knockdown of GATA1 significantly promoted the migration rate and blood vessel formation of HTR-8/Svneo cells (P < 0.001, P < 0.05, respectively) which inhibited by overexpression of NTRK2 (P < 0.05, P < 0.01, respectively).
conclusionsThe study demonstrated that knockdown of GATA1 modulates M2 polarization of macrophage through the TrkB/cGMP-PKG signaling pathway, influencing the progression of PE. In addition, significant associations between GATA1 and the TrkB/cGMP-PKG signaling pathway were identified in the transcriptomic data from PE patient placentas.
