Association between dietary choline intake and bone mineral density in adolescents: a NHANES-based 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
introductionDietary choline has been implicated in bone health, but its association with bone mineral density (BMD) in adolescents remains unclear. This study examines the relationship between dietary choline intake and BMD in adolescents aged 12-19 years. MATERIALS AND
methodsThis cross-sectional study included 2,531 adolescents from the NHANES 2005-2010 dataset, using weighted analyses to account for complex survey design. Dietary choline intake was assessed from two-day dietary recall data, and BMD for the lumbar spine and femur was measured by dual-energy X-ray absorptiometry (DXA). Multivariate regression models adjusted for relevant covariates. Subgroup analyses explored effect modifiers, and a sensitivity analysis with multiple imputation for missing covariates confirmed the stability of results.
resultsHigher dietary choline intake was significantly associated with increased BMD in both the lumbar spine and femoral regions. For each 100 mg/day increase in choline intake, lumbar spine BMD increased by β = 6.75 (95% CI: 0.79-12.70, P = 0.028), and femoral BMD by β = 10.93 (95% CI: 3.58-18.27, P = 0.005). Participants in the highest choline intake tertile (T3) showed significantly higher BMD in the lumbar spine (β = 18.72, 95% CI: 1.84-35.60, P = 0.031) and femur (β = 28.33, 95% CI: 5.03-51,63, P = 0.020). The subgroup analyses indicated no significant interactions across subgroups, confirming the stability of the results. Additionally, sensitivity analyses conducted following multiple imputations of missing covariate data supported these findings.
conclusionsHigher dietary choline intake is positively associated with BMD in adolescents, supporting the potential role of choline in bone health during this critical developmental period.
