Association between dietary choline intake and odds of preeclampsia: a case-control study.

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: Preeclampsia (PE) is a leading cause of maternal and perinatal morbidity and mortality. Choline, essential in one-carbon metabolism and vascular function, may influence placental health. We examined associations of total, subtype-, and source-specific dietary choline with PE odds in Chinese women. Methods: We conducted a 1:1 matched case-control study of 982 pregnant women (491 PE cases; 491 controls) in Zhengzhou, China. Dietary intake over the preceding three months was assessed using a validated semi-quantitative food-frequency questionnaire. Conditional logistic regression calculated odds ratios (ORs) and 95% confidence intervals (CIs) for total choline, lipid- vs. water-soluble forms, and animal- vs. plant-derived sources, adjusting for covariates. Restricted cubic splines explored possible non-linear dose-response associations. Results: Among 982 participants (491 PE cases; 491 controls), mean total choline intake was 335.8 mg/day, with eggs contributing 42.5%. In multivariable-adjusted models, compared with the lowest quartile, those in the highest quartile of total choline intake had 58% lower odds of PE (OR = 0.42; 95% CI, 0.26-0.68), with similar associations for lipid- (0.33; 0.22-0.48) and water-soluble forms (0.37; 0.25-0.54). Both animal- (0.43; 0.30-0.63) and plant-derived choline (0.31; 0.21-0.46) were protective, while their intake ratio was not. Each additional 25 g/day of egg (~half an egg) was linked to an 11% lower PE odds. Conclusion: Higher habitual dietary choline intakes from animal and plant sources were independently associated with significantly lower odds of PE, suggesting that adequate, source-diverse choline intake in early pregnancy may offer a practical dietary strategy for PE prevention.
