Table 1.

Subject demographics.

Subject group	N	Age	M/F	BMI	Type	Duration	NRS
		Years (range)			1/2	Years (range)	(0–10)
Controls	60	40.7 (23–68)	12/48	26.2 ± 0.8	N/A	N/A	N/A
CRPS	160	43.7 (18–68)	29/131	26.9 ± 0.5	124/36	8.6 (0.5–36)	7 (1–10)

This table lists the two groups, the number of subjects (N) in each group, their average age and range in years, the gender ratio (males/females), and the body mass index (BMI, mean ± standard error). In addition, for the CRPS patients, it lists the number of CRPS type 1 and 2 patients, the mean and range of the disease duration (years between initiating event and blood draw) and the median and range of the NRS pain score. There were no significant differences in age (P = 0.12), BMI (P = 0.38), or gender makeup (P = 0.75) between CRPS subjects and controls.
