Study Data (effect size, standard error per study):

Format: effect,SE; effect,SE; ... (semicolon between studies)

Fixed-Effect: Assumes one true effect size underlying all studies.

Random-Effects: Allows for variation in true effects across studies.

I²: Percentage of variability due to heterogeneity (0-25% low, 25-75% moderate, 75-100% high).
