^a Estimates adjusted for age (years), camp enrollment, and race (White non-Hispanics vs. Other).

^b Statistically significant value would indicate intervention and control have different values at baseline.

^c Statistically significant value would indicate that values for intervention and control are changing over time.

^d Statistically significant value would indicate that intervention and control are changing differently over time (interpreted for intervention effect).
