Means, SDs, and statistical tests of ΔSUV max for the QPG methods with sample thresholds stratified by breathing types. (QP: With a distinct quiescent peak at end-expiration; non-QP: Without distinct quiescent peaks.) p-values <0.05 are considered statistically significant.

Breathing types	H-QPG w∕50% counts	C-QPG w∕20% threshold
QP (N=20)	11.5%±14.2%	11.0%±13.1%
Non-QP (N=11)	4.7%±4.7%	6.5%±6.3%
p-value	0.13	0.30
