[Combined]
Average 				8,064100	

Note: This report shows the input data for each study in the analysis. The 'Average' values are
actually weighted averages with weights based on the effects model that was selected.

Nondirectional Zero-Effect Test Using Random Effects Model

	Outcome			Prob
Rows	Measure	Chi-Square	DF	Level
Combined	Mean Difference	228,485509	3	0,000000

Note: This chi-square value tests the null hypothesis that all effects are zero versus
the alternative that at least one study had a non-zero effect.

Directional Zero-Effect Test Using Random Effects Model

	Outcome			Prob
Rows	Measure	Chi-Square	DF	Level
Combined	Mean Difference	225,974017	1	0,000000

Note: This chi-square value tests the null hypothesis that all effects are zero versus
the alternative that all studies had the same, non-zero effect.

Effect-Equality (Heterogeneity) Test

	Outcome	Cochran's		Prob
Rows	Measure	Q	DF	Level
Combined	Mean Difference	2,511493	2	0,284863

Note: This tests the null hypothesis that all effects are equal (homogeneous) versus
the alternative that at least one effect had a different effect (heterogeneous).
Sometimes this test is used to choose between the use of a Fixed Effect (homogeneous) model
and a Random Effects (heterogeneous) model.

[Combined]
Average	8,064100	0,653650	6,988941	9,139259	

Note: This report presents the difference's value and a confidence interval.
The 'Average' line presents the combined estimates for the group. The weights let you
determine the influence of each study on the combined results.
