这项回顾性横断面分析纳入了来自两家医院的26,550张全景X线片。AI模型识别单颗牙齿和种植体,并量化牙槽骨丧失的严重程度。基于这些参数,研究构建了一个0~100分的基于X线片的评分,该评分纳入缺失牙数量及加权后的骨丧失严重程度。研究评估了该评分与5种全身性疾病临床诊断之间的关联:糖尿病、高血压、骨质疏松症、缺血性心脏病和高脂血症。
方法学包括:不同疾病状态组间评分比较、按评分升序五分位分层的患病率趋势分析,以及校正混杂因素(年龄、性别、BMI)的多变量Logistic回归模型。为评估AI评分在仅纳入人口学协变量基础上的增量诊断区分能力,研究进一步采用受试者工作特征曲线下面积(area under the receiver operating characteristic curve, AUC)的变化值(ΔAUC)及DeLong检验进行统计学分析。
