consists of patient clinical and demographic characteristics.
Unfortunately, causation cannot be determined from the data
available.Which research method should be used to test the team's
hypothesis?

Ans: Introduces subjectivity to data collection
Many physician practices now utilize an electronic health record
(EHR) system that includes a secure messaging feature. Some of
these practices have extended their contact with patients by
conducting virtual visits between people with diabetes and nurses
who are certified diabetes educators. The remote technology
includes the ability to monitor blood glucose data to determine if
these values are within goal range. After six months, the results of the
