Covariate (moderator)
Direction of association
Approximate trend
Propofol dosage difference (msg)Positive Each 50 mg increase in propofol appeared to increase LogRR by approximately 0.05-0.10
Mean age (years)Slighty negative Each approximately 10 years increase in mean age appeared to decrease LogRR by approximately 0.01 (very weak)
