Preeclampsia and Eclampsia: A Complex Interplay Between Prepregnancy Obesity, Race, and Ethnicity.

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 and eclampsia (PE/E) are major contributors to maternal morbidity and mortality in the United States, disproportionately affecting Black, Hispanic, and American Indian/Alaska Native individuals. Prepregnancy obesity is a well-established risk factor, but the variation of its association with PE/E by race and ethnicity, particularly among Asian/Pacific Islander (PI) and Hispanic subpopulations, remains unclear.
methodsThis population-based cohort study included 311 497 pregnancies at Kaiser Permanente Northern California from 2011 to 2020. We used Poisson regression to estimate adjusted relative risks (aRRs) for PE/E by prepregnancy body mass index (BMI), stratified by race and ethnicity and adjusted for sociodemographic, clinical, and neighborhood-level factors.
resultsThe overall PE/E prevalence was 4.6%, highest among Black (6.8%) and lowest among Asian/PI (4.2%) and White (4.1%) individuals. PE/E prevalence increased with higher BMI across all groups, but the strength of the association varied. Black individuals experienced the smallest BMI-associated risk increase (aRR for obesity class II-III versus healthy weight, 1.53 [95% CI, 1.28-1.82]), whereas Asian/PI (2.92 [95% CI, 2.59-3.28]) and White (2.81 [95% CI, 2.58-3.07]) individuals had the largest increases. Among Asian/PI subgroups, Filipina individuals had the highest PE/E prevalence (6.2%), and Vietnamese individuals had the largest BMI-related risk increase (aRR, 3.83 [95% CI, 2.20-6.68]). Among Hispanic subgroups, Mexican individuals had the highest prevalence (5.3%) and the largest BMI-related risk increase (2.41 [95% CI, 2.17-2.68]).
conclusionsPrepregnancy obesity is more strongly associated with PE/E risk among Asian/PI and White individuals than Black individuals, suggesting differing underlying mechanisms. These findings can inform refined risk stratification and call for further research into the biological and structural drivers of racial and ethnic disparities in PE/E.
