Placenta location, a prognostic determinant for the incidence of preeclampsia.
Article in BMC pregnancy and childbirth, 2024. 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
backgroundPreeclampsia is one of the complications of pregnancy with uncertain etiology. Nevertheless, it is believed that the condition may arise due to abnormal trophoblastic invasion, resulting in vascular remodeling and increased resistance in the spiral arteries. It is assumed that the location of the placenta might have contributed to the formation of trophoblastic invasion and further placental supply. The current study aims to investigate the association of placental location with the incidence of preeclampsia.
methodsThe current case-control study was conducted on 206 primigravid pregnant woman undergone routine screening ultrasonography study between 14 and 26 gestational weeks to determine the location of the placenta (anterior, posterior, or lateral). The pregnant women were categorized as cases that met the criteria of high-risk for preeclampsia (n = 106) or the controls (n = 100).
resultsLogistic regression analysis identified increased age (OR: 1.047, 95% CI: 1.02-1.07, PPP-value = 0.033), BMI > 25 kg/m² (OR: 4.61, 95% CI: 1.02-10.02, PPP-value = 0.038), and anterior placental location (OR: 2.79, 95% CI: 1.08-9.43, PPP-value = 0.038) as significant predictors of preeclampsia. Posterior placental location was initially associated with preeclampsia (PPP-value = 0.049), but this association was not robust and may reflect random variation.
conclusionThis study identified anterior placental location, increased maternal age, and BMI above 25 kg/m² as significant predictors of preeclampsia. These findings suggest that healthcare providers should closely monitor pregnant women with anteriorly located placentas, advanced age, or elevated BMI. Regular blood pressure monitoring and urine protein screening for individuals with anterior placental location could facilitate early diagnosis and management of preeclampsia. While posterior placental location showed a potential association, it was less consistent, and further research is needed to confirm its role.
