*Significant parameters are only shown in the final model.

OR values <1 are given in black, OR values > 1 in red.

For continuous parameters, the OR values refer to the maximal range of the parameter from minimum to maximum value; no categorization was undertaken.

Wald‘s Chi-square values and p-values are presented in eTable 5.
