	% Agree (95% CI)	Reliability Statistic* (95% CI)
Gender	97.69 (96.35-98.85)	0.95 (0.92-0.98)
CD4 Value	98.40 (97.21-99.40)	0.91 (0.80-1.00)
Patient Retention†	99.23 (98.46-99.81)	0.97 (0.95-0.99)
CD4 Date	92.61 (90.42-94.61)	-
ART Initiation Date	97.88 (96.72-99.04)	-
Outcome Date	95.91 (94.35-97.47)	-

*Kappa score for gender and patient retention; Concordance correlation coefficient for CD4 value; No reliability statistic for date variables since they are highly dependent on the scale of the continuous variable which is arbitrary for date values. †As of July 2008
