The abundant non-dioxin-like congeners were always strongly correlated with each other (correlation coefficient > 0.6), and CB-153 was always very strongly correlated with the Σ3PCB measure (correlation coefficient > 0.9).
As expected, tibia and patella lead levels were strongly correlated with each other (correlation coefficient = 0.78).
Anti-MCV and anti-CCP2 were significantly, but not perfectly, correlated with each other (correlation coefficient = 0.594; p < 0.001 using Spearman's rank correlation coefficient).
In a second step, a multicollinearity analysis was computed with all significant bivariate predictors to eliminate the confounding of predictors that were correlated with each other (correlation coefficient ≥ .50).50
Although these PCB groupings are highly correlated with each other (correlation coefficients = 0.94), we conducted separate analyses to explore potentially different toxicologic mechanisms of action for dioxin-like versus non-dioxin-like congeners (Schantz et al. 2003).
BMI, waist and WHtR correlated highly with each other (correlation coefficient ~0.9, p< 0.001) in both males and females.
When the various parameters were compared with each other, all motility parameters correlated significantly with each other (correlation coefficients varied from 0.44 to 0.81), similarly the plasma membrane integrity tests showed significant correlations between each other (0.37 – 0.37).
In another study, it is reported that educational level was correlated with the anxiety scale of EQ-5D, but no other correlation was identified with either EQ-5D or SF-36 [ 30].
Well, it should be robust, showing up all over the place, across many states and nations; it should exclude some other correlation that might be causing the same thing; and, ideally, there ought to be some kind of proposed mechanism that would explain why one element affects the other.
The potential model is compared with other correlation models proposed in literature.
Nevertheless, any other correlation function can be used (i.e., the classical Jakes' model [18]).
