Correlations between the ABR (auditory brainstem response) and subject characteristics of gender, age, and head diameter were established in simple and multiple regression analyses of normal hearing individuals. The simple regression tests demonstrated that head diameter and gender were significantly correlated with the latencies and amplitudes of waves I, III, and V and the I-V and III-V interpeak intervals. In nearly all cases, head diameter correlated more highly with the ABR waves than did gender. Males had longer latencies than females with comparable head diameter, suggesting that factors other than head size are differentiating them. Age was significantly correlated only with the latency of wave III. All significant subject variables also were compared simultaneously in a multiple regression analysis to determine their order of significance and relative contributions to the ABR wave latencies. This permitted the establishment of regression equations for each wave latency to predict the ABR with measurable subject characteristics.
在对听力正常个体进行的简单和多元回归分析中，建立了听性脑干反应（ABR）与性别、年龄和头径等受试者特征之间的相关性。简单回归测试表明，头径和性别与I、III和V波的潜伏期和波幅以及I-V和III-V峰间期显著相关。在几乎所有情况下，头径与ABR波的相关性都高于性别。在头径相当的情况下，男性的潜伏期比女性长，这表明除头围大小外的其他因素导致了这种差异。年龄仅与III波的潜伏期显著相关。在多元回归分析中还同时比较了所有显著的受试者变量，以确定它们的显著性顺序以及对ABR波潜伏期的相对贡献。这使得能够为每个波潜伏期建立回归方程，以便根据可测量的受试者特征来预测ABR。
