Example Input: Question: Is magnesium sulfate used for pre-eclampsia and eclampsia in Mexico and Thailand as much as it should be?
Answer: Despite compelling evidence, magnesium sulfate use is below desired levels. Clinical practices should be audited and implementation of this effective intervention should be taken up as a priority where universal implementation is not in place.
Example Output: no

Example Input: Question: Do interictal epileptiform discharges have an independent association with cognitive impairment in children with lesional epilepsy?
Answer: Overall, IED effects on cognition were of a magnitude similar to lesional influences or drug effects (topiramate use). This study demonstrates an association between IEDs and cognitive dysfunction, independent of the underlying focal brain pathology.
Example Output: yes

Example Input: Question: Does precessation treatment with nicotine patch significantly increase abstinence rates relative to conventional treatment?

Example Output:
yes
