Another point of view:
Research aside (different studies of the SAME subject too often produce contradictory ressults!), I still prefer the DIGITAL meters on my Z-4000! I have been on hemodialysis for almost seven-years, and during that time frame, I have seen DIFFERENT data produced from studies on the SAME subject that resulted in a change of treatment modality protocols, with frequent reversals! Therefore, I am a skeptic of "studies"! Often, and even with the best of intentions, bias on the part of the observer(s) is a factor in the results!
MY digital meters are VERY easy to "read" (and process) at a glance. Maybe I have been conditioned to them over the fourteen-years (since 1998) I have owned my two Z-4000's!
Aren't there also studies which always produce the same results?
