Frequency-specific hearing trajectories by age for ears with congenital/early-onset SNHL, delayed-onset SNHL, and normal hearing, among symptomatic and asymptomatic case-patients.
Caption: The “spaghetti plots” in the left-hand column fit the raw data using smoothers (i.e. splines). Individual profiles are overlaid with the average trend lines. The plots in the right-hand column show the predicted means of hearing thresholds using the corresponding fixed effects models from ordinary least squares regression.
