Comparison of serum immunoglobulins IgG, IgA and IgM levels (g/L) in yoga and control groups following surgery using paired t test and ANCOVA

Outcome measures	Presurgery	Postsurgery
Serum immunoglobulin G
Yoga mean ± (S.D)	5.6 ± 3.6	5.9 ± 3.8
Control mean ± (S.D)	5.1 ± 2.9	7.3 ± 5.2*
⇕Adjusted mean change scores (y-c)
(95% CI)		-1.5 ± 1.1
		-3.6 to 0.69
Serum immunoglobulin M
Yoga mean ± (S.D)	0.8 ± 0.5	0.9 ± 0.7
Control mean ± (S.D)	0.8 ± 0.5	1.0 ± 0.7
⇕Adjusted mean change scores (y-c)
(95% CI)		-0.2 ± 0.2
		-0.5 to 0.2
Serum immunoglobulin A
Yoga 33 mean ± (S.D)	1.1 ± 0.95	1.13 ± 0.7
Control 32 mean ± (S.D)	1.2 ± 1.05	1.84 ± 1.23**
⇕Adjusted mean change scores (y-c)
(95% CI)		-0.765 ± 0.24**
		-1.24 to -0.29
