Data reported in days as mean (SD) [range]. All patients in the TTI = 0 cohort underwent surgery as registry-reported first treatment. values represent a comparison between effective TTI and reported TTI of 0 days in all patients. ϕ = sarcoma physician and nonsarcoma physician providers were within our health system.
