Vitamin D Supplementation and Cardiovascular Disease Risks in More Than 83?000 Individuals in 21 Randomized Clinical Trials

Please tell me the conclusions drawn are due to inherent flaws in meta studies resulting in agenda dependent outcomes or some such thing...esp from alphabet agency journals. I haven’t read the whole thing...just skimmed through but I would really like someone more fluent in this type of publication to interpret.

Vit D is something we all take not only for bone health but for cardiac health, isnt there something about vit d and vit k being cooperatively beneficial to the human CVS? Thanks
