t-Test for statistical difference in overall mean in each age group: < 5 years (t = 4.185, df = 11.4, p = 0.001); 5 to 19 years (t = 0.264, df = 9.71, p = 0.797); < 20 years (t = 0.746, df = 11.37, p = 0.471).
Two one-sided test (TOST) for statistical equivalence of overall mean in each age group, GBD vs UNICEF: < 5 years (6.9% vs 4.1%, p = 0.375); 5 to 19 years (12.0 vs. 12.4%, p = 0.0.032); < 20 years (10.7 vs. 10.0%, p = 0.024).
