Figure 3: MER-OOPS: correlations of the postoperative air-bone gap (ABG) and the scores of the middle ear risk (MER) index (upper y-axis: data of dB as average value and standard deviation) according to Felek et al. (2010) [57] and the ossiculoplasty outcome parameter staging (OOPS) index (lower y axis; data of dB as average value according to Dornhoffer and Gardner in 2001 [43]. For the OOPS-index, a correlation coefficient of 0.8 is given. The correlation between the increasing scores in the indices and the remaining ABG is clearly seen.
