Fig. 3: Individual pure-tone audiograms (treated ear) of all patients that completed 12 weeks follow-up (N = 42).

Presented timepoints are baseline (black circle), 6 (blue cross) and 12 (red triangles) weeks. Frequencies not shown indicate that thresholds are beyond the maximum output of the audiometer. Pure-tone thresholds are displayed in decibel hearing level (dB HL), frequency in kilohertz (kHz). Source data are provided as “supplementary data 4”.
