Results from forward stepwise linear regression model.

SRT in diffuse noise was the dependent variable. The four predictors in the model were pure-tone average (PTA) threshold in the better ear, word recognition scores (WRS) in quiet, phoneme recognition scores (PRS) in quiet, and thresholds in the better ear at 1000 Hz. Coefficients of the model are shown at left, the results from the analysis of variance (ANOVA) are shown in the middle, and the prediction (r and r2) are shown at right. The asterisks indicate significant effects for the coefficients and the ANOVA results. For the value-inflated factor (VIF) column, the italicized values indicate substantial collinearity among the entered predictors in the model (VIF > 5).
