Adjusted cost: Cost was adjusted for inflation using the Consumer Price Index to 2015 US dollars and winsorized to 3rd and 97th percentiles.
P-value was from Kruskal-Wallis test. IQR: interquartile range.
Multivariable median regression model were fit using interior point algorithm with resampling method (1000 repeats) to compute confidence interval, adjusted for age, year, marital status, race, insurance status, hospital location, teaching status, bed size, region, comorbidity, route of hysterectomy, annualized hospital volume, any complication and lymph node assessment.
