Figure 2. LittlEars validation data from Swedish normal hearing children and the German derived-norm curve. The solid line shows the Swedish normative curve derived through mixed regression model with random intercept and random slope (age) with a quadratic trend with the equation of = 1.0026 + 2.1543×x − 0.0298×x². The bold dotted line shows the original German normative curve with the equation of = 2.0651 + 2.2175×x − 0.376×x². The dotted black lines display the upper and lower confidence intervals of the Swedish sample. The circles represent the raw data of the 299 questionnaires of the 25 participants.
