Fitted regression coefficients of final models of multiple linear regressions of the EMWS Indices.

Note: The unit of the fitted coefficients and the 95% CI are percentage points; Only significant extreme weather variables were selected to the final models by stepwise procedure;- denotes insignificant factors to the EMWS Index for that cause of death;§ Year = 1 denotes the year 1976, year = 2 denotes the year 1977, and so on;# These variables became insignificant when calendar year was included in the model;Multicollinearity was not detected in the final models.Fitted regression coefficients of final models of multiple linear regressions of the EMWS Indices.备注：拟合系数与95%置信区间（95% CI）的单位为百分点；仅通过逐步回归法筛选出具有统计学显著性的极端天气变量纳入最终模型；符号“-”代表针对该类死因的极端天气与死亡率综合指数（EMWS Index）而言无统计学显著性的影响因素；§ 符号中，年份取值为1对应1976年，取值为2对应1977年，以此类推；# 当模型中纳入公历年份变量后，上述变量的统计学显著性消失；最终模型中未检测到多重共线性问题。以下为极端天气与死亡率综合指数（EMWS Indices）的多元线性回归最终模型的拟合回归系数。
