Table 3. Mixed treatment comparison (MTC) model comparing anxiety among treatments.

Anxiety	Direct comparison *	Indirect comparison **
	Difference in means (95% CI)
HI vs. BUR+LA	-1.21 (-3.66 to 1.1)	-5.35 (-6.42 to -4.20)
CHM vs. BUR+LA	--	-5.79 (-7.77 to -3.79)
CHM vs. HI	-0.40 (-0.80 to 0.002)	-0.45 (-2.15 to 1.30)

* Random effects model,—Inverse variance method; DerSimonian-Laird estimator for tau^2; I^2 = 98.7% (97.3%–99.4%).

** Fixed effects model, Model fit: residual deviance; DIC = 19.44. Each chain used 80,000 iterations with a burn-in of 10,000 and a tinning interval of 20.

Negative values represent a decrease in the anxiety levels. Highlighted cells represent contributions from indirect comparisons.
