^aP-values were adjusted for multiple comparisons and are considered significant at P<0.01 (shown in bold); all results found at a P<0.05, however, are provided for this table.

^bSpearman’s r-values are provided when correlation of two continuous parameters are presented; P-values are significant but not provided when the r-value is reported.

^cP-values are presented for results of measures of association not based on correlation of two continuous parameters.
