Table 5.

List of 26 predictors in the Full cox regression model. 17 of them are statistically significant (p-values are computed at α = 0.05 level followed by Bonferroni correction (α/26)). The predictors are listed along with their β weights. se(β) is the standard error of the coefficient. z is the Wald statistic which determines whether the corresponding β is statistically significant. The exponentiated β is the hazard ratio (HR). For example, keeping all the predictor variables constant, an additional proportion of present words used increases the monthly hazard of recovery by a factor of eβ = 35.38, that is by 3.57 percent.
