Abbreviations: 95% CI, 95% confidence interval; HR, hazard ratio; R0, macroscopically complete surgical resection with negative microscopic margins; R1, macroscopically complete surgical resection with positive microscopic margins; R2; macroscopically incomplete surgical resection; WDLPS, well‐differentiated liposarcomas.

P value was determined using the 2‐sided Wald test.

^aThe 2 values were the third and first quartiles, respectively, of the variable distribution.
