Hemodynamic Insights into Preeclampsia: Comparing Ophthalmic and Uterine Artery Resistive Indices.
Article in Medical science monitor : international medical journal of experimental and clinical research, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
BACKGROUND Doppler ultrasonography has emerged as a non-invasive method for evaluating vascular changes in preeclampsia. The ophthalmic artery emerges a novel target for hemodynamic assessment in preeclampsia. This study aimed to compare the Doppler ultrasound pulsatility index (PI) and resistive index (RI). PI and RI in the ophthalmic artery and uterine artery were measured in 60 pregnant women with and without preeclampsia. MATERIAL AND METHODS A cross-sectional design study was conducted to measure Doppler parameters of the uterine and the ophthalmic artery involving 30 participants in preeclampsia and 30 participants in non-preeclampsia groups in West Java from July to September 2024. Doppler ultrasound was performed (Voluson GE S8 BT-equipped with a 7.5 MHz linear transducer, operated by a single maternal-fetal medicine trainee) to measure PI and RI values in the uterine (normal 0.45-0.5) and ophthalmic arteries (normal 0.6-0.7). Bivariate statistical analysis and Pearson correlation tests were performed as further analysis. RESULTS The study found that the uterine artery's PI and RI were significantly higher in the preeclampsia group than in the normal group (P<0.0001). In contrast, the ophthalmic artery's PI and RI were significantly lower in the preeclampsia group (P<0.0001). There was a negative correlation between the RI of the uterine artery and ophthalmic artery, with a coefficient value of -0.19 and statistically significance (P=0.01) in the preeclampsia group. CONCLUSIONS The findings suggest PI and RI changes and a significant correlation between uterine and ophthalmic artery RI values, reflecting systemic endothelial dysfunction in preeclampsia.
