The phrase "a direct causative" is correct and usable in written English.
It can be used in contexts discussing cause-and-effect relationships, particularly in fields like linguistics, philosophy, or science.
Example: "In this experiment, we aim to identify a direct causative between the variables involved."
Alternatives: "a direct cause" or "a straightforward causative".
Despite great progress, a direct causative pathway from the HD gene mutation to neuronal dysfunction and death has not yet been established.
Since oligomeric Aβ is suggested to be a direct causative agent of AD, we believe they may be an ideal predictor of disease progression.
Assuming the genetic associations we identified are real, they may either be due to a direct causative effect of the SNPs tested, or because these tSNPs are in linkage disequilibrium and serve as markers for the real determinant of a disease.
We investigated if such anti-TG2 antibodies have a direct causative role in ataxia by injecting the anti-TG2 (class1), the anti-TG2-3-6 (control or the control (bac1) scFv into the lateral ventricle of mice and tested their effect on balance using the rotarod test [15].
However, the veracity of these alternate hypothesizes appear unlikely given that there is a large body of literature suggesting a close causative relationship between working memory and PFC dopamine and that we recently demonstrated a direct causative relationship between working memory and general learning abilities in mice [42].
Is serum urate a direct causative factor for cardiovascular disease?
However, other lines of evidence support a more direct causative role of zinc in the pathogenesis of T2D.
Consistent with a contributory rather than direct causative role, deletion of the IL-6 gene in mice attenuates sensitivity to the depressing effects of LPS and IL-1 on social exploration and body weight (Bluthe et al., 2000) and using soluble gp130 (sgp130) to block IL-6 trans-signalling also reduces LPS-induced suppression of locomotor activity (Burton et al., 2013).
Finally, we used a cross-sectional design and, therefore, could not examine direct causative mechanisms or the effects of progression of illness.
Because A. punctatum does not bite humans or cause contact dermatitis (2 ), it was not considered as the direct causative agent.
Our study demonstrated direct causative relationship between the regression in moral reasoning development and clinical teaching during medical curriculum.
