Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Large-scale systematic reviews and randomized clinical trials indicate that daily multivitamin supplementation does not provide significant health benefits, such as reducing cardiovascular disease or fracture risk, for healthy adults.

The analysis

The claim asserts that healthy adults should take a daily multivitamin. The provided literature includes a large systematic review and meta-analysis showing no cardiovascular benefits from multivitamins (Paper 0), as well as a recent large-scale randomized clinical trial finding no reduction in fracture risk from multivitamin use (Paper 1). Papers 2, 3, and 4 are completely unrelated. Because rigorous empirical evidence shows no significant health benefits for general multivitamin use, the claim is refuted.
