Author Notes
+Out of 57 tests, there were 4 missing results in the cross tabs (4 missing cervical DNA results of which 2 were also missing for the provider vaginal).
++Out of 57 tests, there were 3 missing results in the cross tabs (2 provider-collected vaginal tests, 1 self-collected vaginal test).
* McNemar’s test used due to the dependency of the data. 95% CI based on exact distribution due to small sample size.
