Cox proportional hazards regression

MALARIA, REGRESSION
The crude hazard ratio (HR) comparing malaria incidence in the intervention and control districts was 0.073 (95%CI 0.054–0.098; p < 0.001). None of the predictor variables had a significant association in univariable analysis. LLIN use the previous night, parental education and socioeconomic status were included in the multivariable cox proportional hazards regression model because of their historical protective influence against malaria. Indoor residual spraying was excluded because it was not being implemented in the study area. The hazard ratio for a positive malaria test remained statistically significant at 0.033 (95% CI 0.014–0.075; p < 0.001).
