CHILDREN AND HEADACHES – AHS PEDIATRIC AND ADOLESCENT TASK FORCE
Statistical Sample Size Calculator (as referenced in the May 2005 issue of Headache) – This calculator has been created to aid researchers in determining the adequacy of their sample sizes and resulting statistical power. Calculations are based on a normal curve test on the arcsine transformation of the proportions.
AHS Headache Profiles
Each issue of the AHS Headache Profiles is a newsletter-style publication that presents a detailed vignette. Each issue is accompanied by brief articles addressing the issues raised in each case. The AHS Headache Profiles have been designed to be equally suitable for formal instruction or self-instruction by residents and students.
