Mean MAA for all participants at each of the three testing intervals. At baseline, 6 children were tested with CI-HA and 4 children were tested with UniCI only. At the 3- and 12-mo intervals, all children were tested both with BICI and UniCI (1st CI only). Group means were computed using only data from participants whose results were measureable at that interval. Number of unobserved datapoints at each interval were: baseline=3, 3-mo=3(BICI) 6(UniCI), 12-mo=0(BICI) 1(UniCI).
