  1. All values were calculated with the χ2 test with 1df unless noted otherwise. In the multivariate model, all bivariately statistically significant variables at p = 0.1 are included and odds ratios are also adjusted for sex. Each variable was adjusted for all other variables in the table. The Hosmer-Lemeshow goodness-of-fit statistic = 5.66 with 8 df (p = 0.69). § These patients served as the reference group
