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 Magnesium and calcium are essential minerals for both maternal and fetal health during pregnancy, with their balance potentially influencing uterine artery function. This study explores the connection between serum magnesium and calcium levels and the presence of a diastolic notch in uterine artery Doppler ultrasonography during the second trimester, a marker that could have significant clinical implications for pregnancy outcomes. MATERIAL AND METHODS In this prospective study, conducted from July 31, 2022, to February 28, 2023, we assessed 60 primigravida women between 18 and 24 weeks of gestation. We measured serum magnesium and calcium levels and analyzed their relationship with diastolic notch presence in uterine artery Doppler ultrasonography, a potential indicator of placental vascular resistance. RESULTS Participants had an average age of 25.7±3.67 years and a BMI of 25±4.02. The mean serum magnesium level was 1.77±0.26 mg/dL, while the mean serum calcium level was 9.1±0.63 mg/dL. Notably, serum magnesium levels were significantly lower in the diastolic notch group compared to the non-notch group (p=0.048), and serum calcium levels were significantly higher in the diastolic notch group (p=0.002). CONCLUSIONS This study suggests a significant association between the presence of a diastolic notch in uterine artery Doppler ultrasonography and altered serum levels of magnesium and calcium. These findings may provide a predictive marker for placental dysfunctions such as preeclampsia and intrauterine growth restriction. Further large-scale studies are needed to confirm these associations and explore their clinical utility.
