Note:

^aArea Under the Curve (AUC) (Standard Error)

^bChildren in this Class are to be discriminated from those in the other Class(es); Significant differences are noted by a superscript letter.

^cp <0.001 for 9 vs. 21 months, p=0.001 for 9 vs. 33 months.

^dp < 0.001 for 9 vs. 21 months, p=0.007 for 9 vs. 33 months.

^ep=0.04 for 9 vs. 33 months.

^fp =0.004 for 9 vs. 21 months, p=0.003 for 9 vs. 33 months.
