^aHosmer–Lemeshow “goodness‐of‐fit” test for the multivariate regression analysis showed a nonsignificant p‐value (p = .2) for the difference between our observed results and the expected results. The nonsignificant p‐value for this test means better fit of the model (the higher the value, the better the fit).

^*Statistically significant.
