Multivariable Logistic Model Predicting Odds of Zero Cases of Infection With Chlamydia trachomatis in Communities

Characteristic	β (95% CI), %	P
Intercepta	−2.13 (−3.10 to −1.16)	<.001
Baseline trachoma prevalence (per 10% increase)	−0.72 (−1.27 to −0.19)	.008
Last treatment coverage (per 10% increase)	0.35 (−0.21 to 0.90)	.22

NOTE. CI, confidence interval.

^aCentered at 50% baseline prevalence of trachoma and last treatment coverage with azithromycin of 75%. The probability of no infection after at least 3 rounds of treatment in a community with 50% baseline prevalence of active trachoma and last treatment coverage of 75% is equal to e^−2.13/(1+e^−2.13) = 0.10.
