Description:

This Master Prompt would focus on converting results from different primary studies into valid and comparable quantitative effect-size measures. It would guide researchers in selecting and calculating mean difference (MD/WMD), standardized mean difference (SMD), Hedges' g, odds ratio (OR), risk ratio (RR), hazard ratio (HR), correlation coefficients, Fisher's r-to-z, ratio of means and other appropriate measures.

Researchers would be guided through effect-direction harmonization, variance and standard-error calculation, confidence intervals, transformations, inverse-variance weighting, conversion between compatible effect measures and management of studies reporting multiple dependent effects. The uploaded abstracts demonstrate substantial diversity in effect metrics, including Fisher's r-to-z, Hedges' g, ORs, SMDs, WMDs and ratio-of-means approaches.
