NOTE. Model 1 is a logistic regression model adjusted for age, year of surgery, SES measure, BMI, PSA, clinical stage, biopsy Gleason sum, race, and center. Model 2 is a logistic regression model adjusted for age, year of surgery, SES measure, BMI, PSA, pathologic Gleason sum, race, center, ECE, SVI, and prostate weight. Analyses excluded missing values for pathologic Gleason sum (0.5% of total values).
ABBREVIATIONS. SES=socioeconomic status; PSM=positive surgical margins; OR=odds ratio; CI=confidence interval
*
p-values for SES measures are for trends across SES quartiles.
