RRR (relative risk ratio) represents the likelihood of moderately or acutely elevated CRP (compared to non-elevated) based on exposure to household conditions, controlling for age strata and sex from individual multinomial logistic models for each exposure. Estimates and standard errors are corrected for clustering by household. Significant results (p<0.05) are bolded.
