Construction of the ABE3-Score.

Presence (1) or absence (0) of the three risk factors stratifies the population into eight groups (Group i–viii). The ABE3-Score pools certain groups to stratify the population into three risk groups. Note that the Groups i–viii (the first column) do not appear in ascending order in contrast to Table 3.

通过对三项风险因素的存在（赋值为1）与缺失（赋值为0）进行判定，可将研究人群划分为八个组别（组别i至viii）。ABE3评分通过合并部分组别，将人群划分为三个风险层级。需注意的是，首列的组别i至viii并未按升序排列，与表3的排布方式存在差异。
