Question: what is the difference between mefenamic acid and paracetamol?
Answer: The mean reduction in headache intensity was 36 ± 11% on mefenamic acid and 27 ± 10% (both mean ± SEM) on paracetamol. While this difference is not quite statistically significant (0.1 > P > 0.05) there still remains a 28% probability that mefenamic acid is twice as potent as an analgesic.
