Dear ctakes developers, May I please have your help on a drug-ner question? I am wondering what the difference between MedicationDosage and MedicationStrength is? My goal is to extract the dosage information for a drug called "methothrexate". I used MedicationStrength to get the number and unit. It seems working for many cases. However, I met some problems when processing the following sentence:
"... #1 Bottle(s)metformin PO undefined Methotrexate (ORAL) 15 MG (2.5MG TABLET Take 6) PO QWEEK , 6 tablets, once a week #24 Tablet(s)Metrocream (METRONIDAZOLE 0.75% Cream)..." I thought the number should be "15", and the unit should be "MG". Instead, I got the number as "15", but the unit as "%". I have no idea where the "%" is from. And the MedicationDosage showed that the value is "24". Would any please help explain the results? I would appreciate your help very much!
