Note: Functions are grouped for matching action in MHAV and EHR. The significance of p -value of the proportion test between MHAV proportions of MHAV and EHR accesses for employees accessed any or both system and MHAV proportions for employees in MHAV and EHR are shown by a superscript alphabet next to the it. We adjusted for the multiple comparisons when we reported the significance. Any p -value that exceeded the corrected threshold does not have a superscript alphabet next to it which indicate the insignificance.
