ASR threshold measured in noise (left) and quiet (right) background conditions, decreased with decreasing LDL. Each symbol corresponds to a subject. Filled symbols: tinnitus. Open symbols: no tinnitus. Circles: men. Squares: women. Rightward arrows indicate that the value plotted horizontally is a lower bound on LDL. Upward arrows indicate that ASR threshold was higher than the highest ASR stimulus level tested. Downward arrow indicates that ASR threshold was below the lowest ASR stimulus level tested. Regression lines are a fit to the data for all subjects (solid line), for men only (dashed lines), and for women only (dotted lines). Data points with arrows were not included in regression fits. ASR threshold was significantly correlated with LDL whether or not the arrowed symbols were included (noise background: r(50) = 0.53, p < 0.0001; quiet: r(50) = 0.68, p < 0.0001; Spearman) or excluded (noise background: r(29) = 0.53, p = 0.0022; quiet: r(27) = 0.40, p = 0.032).
