Results from analyses of sex ratios as a function of IQ are presented for 623 autistic children (487 males, 136 females) and 506 nonautistic, communication-handicapped and behavior-disordered children (374 males, 132 females). Proportionately more autistic females were found to have IQs of 34 or below than above 34. However, a linear trend of an increasing number of males with increasing intelligence was found only for nonautistic subjects. The relevance of these findings to genetic factors and the heterogeneity of autism is discussed.
针对623名自闭症儿童（487名男性，136名女性）以及506名非自闭症、有沟通障碍和行为紊乱的儿童（374名男性，132名女性），给出了作为智商函数的性别比例分析结果。结果发现，自闭症女性中智商在34及以下的比例高于智商高于34的比例。然而，仅在非自闭症受试者中发现了随着智力增加男性数量呈线性增加的趋势。讨论了这些发现与遗传因素及自闭症异质性的相关性。
