Abbreviations: FV, fluorescence visualization; IQR, interquartile range; WL, white light.
a
Died of disease includes 14 deaths due to distant metastasis (WL, 8; FV, 6); died of other causes includes 24 deaths before 36 months (WL, 11; FV, 13).
b
Excludes those who experienced a local recurrence before 36 months.
c
Excludes those with a local recurrence at any time.
