Results of ML Analysis of Main/Internal Validation Study Data on 904 Women at the 4^th HERS Visit (n_m=690, n_v=214): Estimates of eqn. (20)^a Describing SE/SP of X* (WET TRICH).

ML estimates of coefficients in eqn. (20)
Variable	δ̂ (95% CI)	p-value
Culture Trichomoniasis (+ vs. −)	4.13 (2.39, 5.87)	<0.0001
LAB BV (+ vs. −)	0.45 (−0.26, 1.16)	0.21
HIV Risk Cohort (IDU vs. Sexual)	1.28 (0.55, 2.00)	0.001

ML estimates of parameters in eqn (20) are obtained by jointly modeling eqns (1) and (18)–(20).
