correlative

“What I tell people is that these studies are correlative, not causative,” says Weiss.

Swan added, "Separating the causal from the correlative is extremely difficult, as you know!"

Because it is indeed difficult to separate the casual from the correlative, even the authors of the new Nature Climate Change agree that further research is needed to prove those links are more than correlation.

Additional studies with larger cohorts of patients and correlative imaging beyond three months may help determine the therapeutic role of light in traumatic brain injury.

To confirm that these glycan-associated disruptions were causal rather than merely correlative, the research team engineered HIV-specific antibodies designed to exhibit the same kind of aberrant IgG glycan modifications observed in PLWH.
