Results of the multivariable logistic regression for factors associated with Schistosoma sp. egg positivity

	Variables	Odds ratio	95% confidence interval	P value
Main effects on egg positivity	HIV infection	0.6	[0.4, 0.8]	0.004
	Female sex	0.4	[0.3, 0.5]	< 0.001
	Serum CAA level (natural log)	1.2	[1.1, 1.3]	< 0.001
With interaction allowed	HIV infection for male	0.4	[0.2, 0.7]	0.001
	Female sex for HIV-uninfected	0.4	[0.3, 0.5]	< 0.001
	Serum CAA level (natural log)	1.2	[1.1, 1.3]	0.003
	HIV*sex (ref = male)	1.9	[1.0, 3.8]	0.069

CAA = circulating anodic antigen.
