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).

Use of Ganoderma lucidum (Ganodermataceae, Basidiomycota) as Radioprotector
Nutrients (2020) · Meta analysis
From a total number of 1109 records identified, 15 full text articles were eligible, none of them were clinical trials.
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 systematic reviews identifying immunostimulatory properties. Meta-analysis for cancer adjuvant therapy showed positive immune response (RR 1.50). Quality clinical data still needed. Effect varies significantly by extract type and standardization.
