Implementing the Mantel-Haenszel estimator in a Meta-analysis
The M-H estimator can be used in situations with less than 10 studies in a Meta-analysis. We will use a similar Python implementation as before, but this time, we will use a specific argument to change the estimator. If you change the setting of the algorithm to MH, we can implement the MH method which is more appropriate for this meta-analysis (having four studies):
# Define settings
settings = {
    "datatype": "CATE",  # 'CATE' for binary data or 'CONT' for continuous data
    "models": "Random",  # 'Fixed' or 'Random'
    "algorithm": "MH",  #  Mantel–Haenszel method
    "effect": "RR"  # RR/OR/RD for binary data; SMD/MD for continuous data
}
# Perform the analysis...
