There was no strong correlation between total annual deaths attributed to the 3 different influenza types and at most weak correlation between their year-specific regression coefficients (Web Figure 5).
Following this, we investigate the behavior of individual AR families, finding that although most families exhibit weak correlations, a few appear to be more strongly correlated due to the influence of purifying selection.
Most phenotypes from the choice trials also were strongly intercorrelated, with the exception of the number of approaches to the plant, which was weakly correlated with most other variables (we define "weak" correlations as those with Rho < 0.3).
However, the most probable cause of the weak correlations observed is their use of log expression ratios, rather than log expression values, as the basis for their correlations.
The results show that 15 of 406 pairs of traits (7.2%) have high-level positive correlations, while most of the pairs have weak correlations (75.2%).
The most likely explanation for the weak correlations among dysregulation scores of different systems is that there are feedback effects among the systems.
In contrast, most genes exhibit moderate to weak correlations with other genes, such that the mean correlation in a typical gene co-expression network is close to 0 and follows an approximately normal distribution (e.g. Figure S2D; Additional file 1).
In the complete network, every node is linked to all other nodes with most of the links representing very weak correlations.
The non-significant or weak correlations between the physical functioning scale and most other measures does not correspond with most previous studies.
Consistently, most dioxin like chemicals did not correlate with PCB101 and PCB52, and showed only weak correlations with PCB128 and PCB28.
