Mediation model (standardized) coefficients and 95% confidence intervals (Fig 6).

*,†p < 0.05, bias-corrected bootstrap confidence interval, 5,000 repetitions. Factors included based on statistical significance in multiple regression on pain (t test, p < 0.05). All parameters and statistics estimated while modeling participant fixed effects (not shown). (XLSX)*、†标记的结果p < 0.05，采用偏差校正自助法置信区间（bias-corrected bootstrap confidence interval），重复抽样次数为5000次。纳入分析的因素基于疼痛相关多重回归分析的统计学显著性筛选（t检验，p < 0.05）。所有参数与统计量均在构建参与者固定效应模型时估算，具体结果未展示。 （XLSX）
