CL, confidence limit; MDASI, MD Anderson Symptom Inventory.

“Recovery to mild severity” was defined as a report of MDASI symptom scores ≤3 (none or mild) at 2 contiguous measurements.

^†

“Recovery to preoperative (baseline) severity” was defined as a report of MDASI symptom levels at or below the preoperative (baseline) level at 2 contiguous measurements.
