Freeman-Tukey double-arcsine transformations were used to stabilize variance as complications were rare.
2
Stage I or limited stage proportions were pooled by random effect model with Freeman-Tukey double arcsine transformation.
3
Study-specific prevalence estimates for clinical features were transformed using Freeman-Tukey arcsine transformation, allowing for pooled estimates of prevalence to be generated using random-effects models.
1
Because arcsin transformation both decreased differences among means and reduced the variance to a lesser extent, it decreased power to detect differences among groups.
2
Arcsin transformation made the distributions closer to normal distributions.
