NA, not applicable; OR, odds ratio, SUVmax, maximum standardised uptake value; 95% CI, confidence interval. Reference group indicates that the corresponding variable had a significant influence on adrenal metastasis. NA indicates that the odds ratio was not performed owing to small or zero count.
a
p=0.321 in Hosmer and Lemeshow test indicates that the multivariate model fit well.
b
p=0.686 in Hosmer and Lemeshow test indicates that the multivariate model fit well.
c
p=0.136 in Hosmer and Lemeshow test indicates that the multivariate model fit well.
