  1. Data are shown as odds ratios with 95% confidence intervals in parentheses. Multivariable logistic analysis was performed with backward elimination using penalized maximum likelihood estimation with variables for which statistically significant correlations were found in the univariable analysis
  2. RVRIs, Revisits with repeat imaging; D-RT, delayed radiology reporting time; OR, odds ratio; CI, confidence interval
  3. *p values < .05
