  1. An asterisk (*) is used to denote p values less than 0.05 for comparisons within each group. Fewer than 7 participants reported their race to be any race or combination of races other than white and are reported as “other”, for example, Black, Indigenous, or other person of color. Fewer than 7 participants reported an ethnicity other than non-Hispanic, therefore, ethnicity is not reported here.
  2. µg/L microgram per liter, GM geometric mean, GSD geometric standard deviation.
