Weighted absolute mean difference between dates on the case report and the medical record

Dates	Weighted Absolute Mean Difference (days)	Coefficient of Variation (C.V.) %
Month/day/year dates
Birth date	48.4	39.9
Treatment start	2.6	17.0
Isolate collection for drug susceptibility testing	13.0	26.1
First positive culture	6.1	31.0
First consistently negative culture	25.0	15.1
Treatment stop	19.2	11.3
Isolate collection for final susceptibility testing	110.9*	44.5
Dates	Weighted Absolute Mean Difference (months)	Coefficient of Variation (C.V.) %
Month/year dates
Case reported to local health department	0.74	10.0
Entry into U.S.	11.5	20.2

Note: All results are presented as survey-weighted mean estimates for the statewide cohort from which the sample was drawn.

* Based on small number of cases with final susceptibility testing performed; therefore estimate is subject to considerable instability
