Instead of assuming that continuous variables such as age and the categorical variable Killip class were linearly associated with risk, we tested for non-linear associations and included them in the revised prediction tool where appropriate.
We find a very significant U-shaped (quadratic) association between BMI BMII) and depression (p ≤ 0.001), continuous BMI is not linearly associated with depression (p = 0.514).
Aboveground biomass was linearly associated with plant density.
Higher cumulative doses of epinephrine were linearly associated with worse outcomes compared with lower doses of epinephrine.
Words spoken only once (V 1) and the total vocabulary used (V) have been shown to be linearly associated.
In Trial 2 we observed relevant differences in UCY across groups, but such differences were not linearly associated with MCP.
Previous research suggests that the relationship between antihypertensives and fractures is linearly associated with increasing dose (Butt and Harvey 2015; Lipsitz et al. 2015).
Increased substrate HS concentration was linearly associated with increased recovery of above ground biomass, indicative of positive covariance between these two variables.
However, the total shed-load is linearly associated with the shed-load due to intermittent effects and outages, and they can be weighted in accordance with their contributions.
Our study confirmed that short-term PM10 exposure was linearly associated with significant increases in both mortality incidence and years of life lost.
