In a double blind experiment, long term pain care patients
In a double blind experiment, long term pain care patients were randomly assigned to either take Embeda (Morphine sulfate and Naltrexone hydrochloride) or Kadian
(Morphine sulfate) for a 6 week period, participants were given an appropriate starting dosage of the medication based on their previous therapy dosing determined by
their respective physician. Of 24 people given Embeda, 14 were able to manage their pain with the starting dosage at the end of the 6 week, whereas in the Kadian
group, only 4 of 24 were able to manage their pain with the starting dosage at the end of the 6 week period. Whether a patient maintains the same dose throughout the 6
week period is of particular importance to researchers, as it suggests the medication is stable/effective for pain management.
6. Organize these data/results (i.e. frequencies) into a two-way table.
