Reyes found that the average levels of lead in gasoline and blood lead levels in children were correlated (r = 0.54) and the correlation increased to 0.84 if data from CA, NY and DC were excluded.
Therefore, when considering all extinct trajectories scenarios, demographic and genetic extinction times were only moderately correlated (Kendall's τ = 57%), but correlation increased when considering only scenarios with a constant environment (τ = 78%).
Another VA study found that PPR and the Centers for Medicare & Medicaid Services CMSS) all-cause readmission measure were moderately correlated; when the variable of potential preventability was removed from the analysis, correlation increased [ 18].
High levels of phosphorylated Akt correlated (P < 0.01) with poor prognosis, and the significance of this correlation increased (P < 0.001) in the subset of patients with ErbB-2 overexpressing tumours.
For example, the PSA severity score at baseline was correlated 0.19, in both studies, with PASI scores, but at 12 weeks this correlation increased to 0.57 in Study A and 0.53 in Study B. Similar patterns of small to moderate correlations were observed for the two itch scales and the PASI and OLS.
But the correlation increased after adjustments were made for country level differences in body mass, population and gross domestic product.
This association was improved by the incorporation of MDR staining via subtractive normalization (Spearman correlation increased to 0.47, p < 0.001).
Moreover, different trends appear before and after the reform: correlation increased in France and Spain, whereas it was rather stable in Poland and reversed in the UK.
Nevertheless, although the correlation increased slightly, it was still nonsignificant (in part due to the reduction in the new sample size).
However, while resting BOLD connectivity pattern expanded and bilateral correlation increased under 100% O2, the correlation coefficient between the left and right somatosensory cortex was generally not dependent on paCO2 or paO2.
