The best way to address heterogeneity in a meta-analysis is to analyze the included studies by dividing them into groups based on factors that may contribute to the heterogeneity. This allows for a more accurate analysis of each subgroup and can help identify underlying sources of variability. Simply analyzing all studies as one group or excluding outliers may not fully address the issue of heterogeneity. Adding more studies may help increase the overall strength of the meta-analysis but may not directly address the heterogeneity.
