Data Input for Interconversion Between Risk Difference, Risk Ratio, and Odds Ratio
   - Two columns separated by white spaces
      -Each row a set of data to be converted
      -Column 1 is the value to be converted, Risk Difference, Risk Ratio, or Odds Ratio
      -Column 2 is the Patient Expected Event Rate (PEER).
      -As the common practice is to designate Group 1 as the group of interest or intervention,
        and group 2 as the control, background, or population value group,
        PEER is the same as risk or proportion of positives in group 2.
