Income-based difference in number of disease-specific healthcare encounters the last 5 years of life. Adjusted and unadjusted RRs (Q1/Q5) in 2017, 2004, and yearly change of log-transformed RR.

aModel 1: negative binominal regression testing for relative group differences (Q1 vs. Q5) in number of healthcare encounters controlling for age, age squared, sex, country of birth, and civil status. bModel 2: unadjusted. cModel 3: same as Model 1 but also controlling for county. dP values associated with the OR indicate significant deviations from the null hypothesis of RR = 1.0, as calculated using Wald tests. eBeta is the estimated value of yearly change in log-transformed RR and is calculated by regressing log-transformed RR on time. The 95% confidence intervals (CIs) were obtained by bootstrapping.

a模型1：针对医疗服务就诊次数的Q1组与Q5组相对组间差异开展负二项回归（negative binominal regression）检验，控制变量涵盖年龄、年龄平方、性别、出生国家及婚姻状况。b模型2：未进行校正调整。c模型3：与模型1设定一致，但额外加入县域作为控制变量。d与比值比（OR, Odds Ratio）关联的P值代表相对风险（RR, Relative Risk）=1.0的原假设存在显著偏离，该结果通过Wald检验（Wald tests）计算得到。eBeta值为经对数转换后的相对风险的年度变化估计量，其计算方式为将对数转换后的相对风险对时间进行回归分析。95%置信区间（confidence intervals, CIs）通过bootstrap重抽样法（bootstrapping）获取。术语说明：心血管疾病（CVD, cardiovascular diseases）、神经系统疾病（Neuro., neurological disorders）、慢性呼吸系统疾病（Chro.Resp., chronic respiratory diseases）、糖尿病与慢性肾脏病（DM & CKD, diabetes and chronic kidney diseases）、住院诊疗服务（Inp., inpatient care）、专科门诊服务（Outp., specialized outpatient care）、基层医疗服务（Prim., primary care）。数据集格式为XLSX。
