DOIPLOT: Stata module for visualization of asymmetry and heterogeneity in meta-analysis
Chang Xu, Luis Furuya‐Kanamori, Suhail A.R. Doi · RePEc: Research Papers in Economics · 2021
doiplot generates the Doi plot and its variants (combinations with the funnel and Galbraith plots). The plots also include the LFK index and Egger's test P-value as a note. The Doi plot replaces the conventional scatter (funnel) plot of precision versus effect with a folded normal quantile (Z-score) versus effect plot. Combined with the Galbraith plot, the Doi-Galbraith plot delivers a combined graphical overview of both study symmetry and heterogeneity at a glance.
