Linear regression results for correlation between EAC obstruction (left (treated with PG) and right (treated with CP)) and cerumen removal time (considering cerumen removal time as a dependent variable)
| Dependent variable | Independent variable | ||||
|---|---|---|---|---|---|
| Cerumen removal time of left EAC | Left EAC obstruction (treated with PG) | ||||
| r | B | r2 | p-value | Formula | |
| 0.40 | 15.32 | 0.16 | 0.02* | 14.77 + 15.32 (left EAC obstruction degree) | |
| Cerumen removal time of right EAC | Right EAC obstruction (treated with CP) | ||||
| r | B | r2 | p-value | Formula | |
| 0.37 | 13.49 | 0.13 | 0.05* | 7.58 + 13.49 (right EAC obstruction degree) | |
*significant correlation between cerumen removal time and EAC obstruction. Abbreviations: r – Pearson’s correlation coefficient; B – Model coefficient; r2 – square of Pearson’s correlation coefficient; PG (Phenol Glycerol); CP (Carbamide Peroxide); formula predicts the cerumen removal time based on the degree of EAC obstruction.
