Model results examining the moderating effect of emotional distress level (low, moderate, or high) on the relationship between physical activity (step count) and HRV (log-transformed RMSSD), adjusting for covariates. Low emotional distress level was the reference level.

本模型结果分析了情绪困扰水平（分为低、中、高三个等级）在身体活动（步数）与心率变异性（Heart Rate Variability，HRV，对数转换后的RMSSD）之间关联的调节效应，并对协变量进行了校正，其中以低情绪困扰水平作为参照组。
