Association of choline and betaine with the risk of cardiovascular disease and all-cause mortality: Meta-analysis
European journal of clinical investigation (2023) · Meta analysis · n=33009
Random-effects model results showed that highest versus lowest quantile of circulating choline concentrations were associated with the risk of CVD (RR = 1.29, 95% CI: 1.04-1.61) and all-cause mortality (RR = 1.62, 95% CI: 1.12-2.36).

Nutrition research (New York, N.Y.) (2024) · Meta analysis · n=482778
This study showed that each 100 mg/day increment in choline consumption was significantly associated with a 6% and 11% higher risk of all-cause and cardiovascular disease mortality respectively.
Activity of Choline Alphoscerate on Adult-Onset Cognitive Dysfunctions: A Systematic Review and Meta-Analysis

CDP-choline for cognitive and behavioral disturbances
Cochrane Database of Systematic Reviews (2006) · Systematic review · n=4000
Positive effects on memory
Based on meta-analysis of α-GPC with donepezil showing cognitive benefits and citicoline studies. Effects vary significantly by choline form - α-GPC and CDP-choline show higher bioavailability. Most evidence is in older adults or those with existing cognitive impairment.
Based on meta-analysis showing SMD 0.56-1.57 for cognitive status improvement. Conservative estimates due to heterogeneity across studies and varying populations (stroke, dementia, TBI). Effect sizes modest and studies show mixed quality levels.
AI-estimated from published studies. Interpret as directional guidance.
Choline has a higher evidence score (9/10 vs 8.5/10) and wins in 2 of 3 categories.
For sharpen focus, Citicoline has a higher relevance score (88 vs 80).
