Lead exposure has also been established as a risk factor for schizophrenia, the lead correlations suggesting environmental chemicals as a new class of schizophrenia risk factors that are still inadequately investigated.
Tibia lead correlated highly with patella lead (Spearman correlation coefficient = 0.62), and both tibia and patella lead correlated moderately with blood lead (Spearman correlation coefficients: tibia = 0.29; patella = 0.34).
However, fewer points may lead to correlation exiting between the samples.
The authors' most recent study is FEXHE-BIO, determining foetal exposure to lead and correlation with environmental indicators including lead in moss and topsoil.
When patients receive treatment in groups, interactions between patients may lead to correlation of outcomes of patients in the same group [ 52] sometimes referred to as cluster.
Fig. 1 Cross-correlations in the Gaussian variables lead to correlations of coincident level crossings.
This dependence structure leads to correlation among test statistics, which leads to under representation of the smallest p-values [ 15].
In addition, when substitutions are at phylogenetically informative sites, then correlations in the substitutions can lead to correlations in tree topology.
We note that the correlation-based network structure used to guide the distal association tests will likely lead to correlations among test statistics.
