^a NA indicates that either the concentration values or case values were all 0 for a state, which meant no Kendall’s rank correlation coefficient could be calculated. n represents the number of observations in each group (state) and an asterisk next to the state abbreviation indicates that the correlation had a P-value less than 0.05. DC is Washington DC.

^b Bolded states represent significant correlations.
