SSC problematic GI symptoms results.

The previous and current percent of ASD children and NT siblings having a problematic GI symptom is listed below. The previous percent were based on parental responses to the SSC medical form for ASD children only on first entering the SSC registry. The current percent were based on parental responses to the same forms for both ASD and NT siblings during the current study ~2–3 years later. The P-values reflect comparison of the current responses of the ASD and NT siblings. There was no significant change in the prevalence of any of the seven problematic GI symptoms in the ASD children at the two time points.以下列出了孤独症谱系障碍（Autism Spectrum Disorder, ASD）儿童与神经典型（Neurotypical, NT）同胞出现异常胃肠道（Gastrointestinal, GI）症状的既往与当前占比。既往占比仅针对首次加入SSC注册库的孤独症谱系障碍儿童，其数据来源于家长填写的SSC医学表单反馈。当前占比则来源于本项研究开展约2~3年后，孤独症谱系障碍儿童与神经典型同胞的家长填写相同表单的反馈结果。本次研究中的P值（P-value）用于对比孤独症谱系障碍儿童与神经典型同胞的当前问卷反馈情况。在两个时间节点下，孤独症谱系障碍儿童所出现的七种异常胃肠道症状中，任意一种的患病率均未发生显著变化。
