Results of stepwise MLRA with denture plaque as the dependent variable (n = 222).

Denture plaque scores were dichotomized using the median (1.67) as a cutoff value (≤1.67, >1.67). Independent variables included duration of denture use, denture wear status, and cleaning and overnight storage methods. Omnibus tests of model coefficients indicated that the χ2 value of the logistic regression model was 40.129 and the P value was研究以中位数1.67作为截断值，将义齿菌斑评分进行二分法处理（≤1.67、>1.67）。自变量涵盖义齿佩戴时长、义齿佩戴状态、清洁方式及夜间存储方法。模型系数综合检验结果显示，该逻辑回归模型的卡方值为40.129，P值为
