Table 2 Calculation of the Consentaneity Index (CI) (i = number of CI intervals examined; n = number of simultaneously appearing CPR documentation within the individual CI interval; nall = number of forms examined within the study (i.e., 4); ndata = number of forms with CPR data; ∆ = operator for the Gaussian partial sum with ∆x = x(x + 1)/2)
a) Standard CI: | |
\( CI=\left(\sum \limits_1^i\varDelta n\right){i}^{-1}{\left(\varDelta {n}_{all}\right)}^{-1} \) | |
b) Soft CI: | |
\( {CI}_{soft}=\left(\sum \limits_1^i\varDelta n\right){i}^{-1}{\left(\varDelta {n}_{data}\right)}^{-1} \) |
