Method 1
SMDs. Weights based on adjusted standard errors
|
18
|
Fixed effects
SMD 0.14(95% CI 0.10 to 0.17)
Random effects
SMD 0.31(95% CI 0.14 to 0.51)
|
I2 = 95.3%
|
Method 2
Separate analyses for binary and continuous data. Weights based
on adjusted standard errors
|
OR 12
SMD 7
|
Fixed effects
OR 1.13(95% CI 1.06 to 1.20) SMD 0.50(95% CI 0.42 to 0.59)
Random effects
OR 1.13(95% CI 1.06 to 1.20)
SMD 0.92(95% CI 0.11 to 1.73)
|
I2 = 0%
I2 = 98.0%
|
Method 3
SMSs. Weighting by number of HCP
|
18
|
SMD 0.57(0.50 to 0.64)
|
I2 = 98.5%
|
Method 4
Albatross plot
|
18
|
All studies reported a positive effect so clear evidence of treatment
effect.
|
Points not clustered around a single contour line so high levels of
heterogeneity
