Pass/not pass outcomes comparison by demographic categories, by year and across years.

Screening outcomes given as number of children (n). Statistical analyses (logistic regression) of outcomes by demographic categories with odds ratios and 95% confidence intervals, and analyses (Fisher’s Exact or Chi-Squared test) of each category across years are shown. Where type 3 p-values were not statistically significant, pair-wise analyses not presented.

筛查结果以儿童人数（n）的形式呈现。本数据集包含两类分析结果：其一为按人口统计学类别对筛查结果开展的统计分析（逻辑回归，logistic regression），同时报告了比值比（odds ratios）与95%置信区间（95% confidence intervals）；其二为各类别跨年度的分析，分析方法采用Fisher精确检验（Fisher’s Exact test）或卡方检验（Chi-Squared test）。当Ⅲ型p值未达到统计学显著性时，未展示两两比较分析结果。
