Table 1.

In the primary PET comparison (i.e. n=12 PASC vs. n=43 control), an unpaired t-test or Chi-square revealed no significant difference between PASC and control groups in age, genotype frequency, BMI, or injected dose. Reflecting the sex distribution of PASC (Bai et al., 2022), there was a higher proportion of female participants in the PASC group relative to the larger historical control group. In this primary analysis, we statistically controlled for genotype and sex.

	PASC	Control	Statistics
Age mean (SD)	47.25 yr (14.19)	50.86 yr (14.19)	t(53)=0.84, p=.20

Genotype count	GG=5, GA=7	GG=27, GA=16	X2 (1.55)=1.72, p=.19
BMI mean (SD)	27.25 (5.01)	26.19 (4.96)	t(53)=0.66, p=.51
Injected Dose	13.64 mCi (1.90)	13.26 mCi (1.58)	t(53)= 0.70, p=.49
