Data on costs do not exist, but a comparison of organization types under asset specificities can indirectly identify effectiveness and efficiency.
Sensitivities and specificities of different LVH voltage criteria were calculated for three groups: 1) all patients with anterior wall MI, with and without lateral wall MI; 2) patients with anterior wall MI and without lateral wall MI; and 3) patients with anterior wall and lateral wall MI.
This means that the sensitivities and specificities are calculated from the data at hand across all possible cutoff values within the range of the test results, with the cutoff value leading to the highest Youden index then being selected.
The historical limits and C1 and C2 methods showed varying sensitivities (44%-71%), with C1 and C2 having the highest, but all demonstrated similar specificities (96%-97%).
Considering each sinus separately, the lowest sensitivities were for the left maxillary sinus and right ethmoidal sinus (48 and 50%, respectively); the lowest specificities were for the ethmoidal sinuses (78 and 84%, respectively), whereas the specificity of all other sinuses was above 90%.
