Table 1

Demographic matching of UDP to non-UDP subjects.

	Obese		Non-Obese
	UDP (n=10)	No-UDP (n=20)	UDP (n=12)	No-UDP (n=26)	P-value
Age, years (mean +/- SD)	59 +/- 11	60 +/- 6.4	64 +/- 9	61 +/- 11	P = 0.31
Male Gender, n (%)	6 (60)	12 (60)	11 (92)	22 (92)	P = 0.14
Right-Sided (proportion)	5/10	-	7/12	-	NS
Duration UDP (mean yrs)	2.8 +/- 1.6	-	2.2 +/- 1.3	-	NS
BMI (mean +/- SD)	34.2 +/- 6.3	33.0 +/- 2.7	26.9 +/- 1.5	25.4 +/- 2.6	<.0001
Comorbidities, n (%)
Cardiovascular	3 (30)	6 (30)	6 (50)	14 (54)	P = 0.41

Joint/Pain syndrome	1 (10)	2 (10)	1 (8)	2 (8)	P = 1.0

Numerical values are reported as mean +/- standard deviation.
UDP = unilateral diaphragm paralysis.
For the difference between obese and nonobese groups, using Wilcoxon rank-sum test and Fisher’s exact test as described in the Methods.
