CI group: n = 54 at 18 months, 37 at 36 months. AIBL (whole) group: n = 47 at 18 months, 17 at 36 months. HL-only group: n = 30 at 18 months and 11 at 36 months. Negative scores indicate improvement, except for visual learning (OCL), which is scored in reverse. Bolding denotes significant p-value after Holm–Bonferroni correction.
