The mean postoperative C-levels in patient groups with different types of CI: Group 532 (n = 54, n = 54), group 512 (n = 54, n = 54) and group 522 (n = 51, n = 51) at first fitting (a) and 2-month follow-up fitting (b). The “*” stands for a significant difference between groups 532 and 522. Error bars represent the standard deviation (SD). Grand T532–512 means statistical comparison between groups 532 and 512. Grand T532–512 means statistical comparison between groups 532 and 522
