Data analysis will be performed using individual growth curve analyses with a multi-level regression model. P values of <0.05 will be considered statistically significant. An intention-to-treat analysis will be performed. If results are found to be significant, a Benjamini-Hochberg adjustment for multiple comparisons will be done. The expected time commitment for each patient will be 15 minutes in the ED and 20 minutes total for 4 follow-up telephone phone calls.
