Mann-Whitney test results for temporal changes in the diagnosis-to-classification time of 343* officially confirmed SARS-CoV cases with classification during period 1,† period 2, and period 3, Taiwan, 2003
Interval (d) | Period 1 (N = 103) | Period 2 (N = 114) | Period 3 (N = 126) | Mean difference (p value) |
---|---|---|---|---|
Diagnosis to classification | 9.1845 | 8.2368 | – | 0.9477 (0.7729) |
Diagnosis to classification | – | 8.2368 | 5.6508 | 2.5860‡ (< 0.0001) |
*2 cases were deleted from the data for our comparison test because of missing information on the relevant dates, and 1 case was deleted because classification as probable case did not occur during the 3 time periods of 2/25–6/15.
†Period 1, time from onset of first case to the day before implementation of intervention measures including Level B quarantine; period 2, time from implementation of intervention measures to the implementation of expedited classification procedure; period 3, time of the expedited classification procedure to the date of onset of the last SARS case.
‡Denotes significance at the 1% level.
