Table 3. Comparison of ICG fluorescence outcomes between obese and non-obese patients.

Characteristics	Obese* (BMI ≥25 kg/m2)	Non-obese (BMI <25 kg/m2)	P-value
No. of patients	10	10	-
PPV	6/10 (60.0)	10/10 (100.0)	0.087
Interval time† (sec)	23.2 (18–28)	21.2 (14–30)	0.315
Arterial phase† (sec)	18.3 (10–30)	14.0 (9–20)	0.190
Total procedural time† (sec)	40.9 (30–57)	36.2 (24–47)	0.353

Values are presented as number of patients (%) or mean (range).

ICG = indocyanine green; BMI = body mass index; PPV = positive predictive value; WHO = World Health Organization.

^*The WHO definition of obesity in the Asia-Pacific region; ^†Mann-Whitney U test was applied.
