question
Is elevated plasma TMAO a cause of cardiovascular disease in humans, or a non-causal marker?
statement
Elevated plasma TMAO is not itself atherogenic in humans: it is a non-causal marker (of impaired renal clearance, gut dysbiosis, or an unhealthy background dietary pattern) rather than a cause of cardiovascular disease, so the choline->TMAO findings do not establish a causal harm pathway in people.

Constructed complement: the null pole no curated paper asserts outright but that the cluster’s logic requires. It is the marker-only alternative against which the causal claims H-15 (animal-model mechanism) and H-16 (human clinical causality) are tested, and the member a confounded/reverse-causation reading of the human associations would favour.
