Incidence of malaria by age, bednet usage, area of residence and treatment group.

*risk differences compared to the SP+1AS group are: SP+3AS, 0.81% (95%CI −2.7%, +4.4%); 3AQ+3AS −1.3% (−5.0%, +2.5%); and SP+3AQ 4.7% (+1.5%, +7.8%).
#based on data for 1968 individuals who were followed up and had covariate data. Crude hazard ratios, including those with missing covariate data, were 0.92, 1.14 and 0.50 for SP+3AS, 3AQ+3AS and SP+3AQ respectively.

* 与SP+1AS组相比的风险差（risk difference）为：SP+3AS组为0.81%（95%置信区间：−2.7%，+4.4%）；3AQ+3AS组为−1.3%（−5.0%，+2.5%）；SP+3AQ组为4.7%（+1.5%，+7.8%）。
# 本分析基于1968名完成随访且具备协变量（covariate）数据的受试者；包含协变量数据缺失者在内的粗风险比（crude hazard ratio），针对SP+3AS、3AQ+3AS与SP+3AQ组分别为0.92、1.14与0.50。
