Eight separate multivariate analyses.
Age was forced into each model and did not influence the results (data not shown).
The presence of at least one schistosome ova in any of the urine examined specimens.
Odds ratio (OR) with 95% confidence interval (CI).
Adjusted odds ratio, different confounding variables were included in each multivariate analysis for the specific genital symptom.
Red urine as seen by the child.
If recalculated as ‘ever had the symptom’ it is significantly associated with urinary schistosomiasis.
