Incidence of solicited adverse events reported by mother or carer four days day after the first administration of IPT.

Intraclass correlation coefficients for each outcome were as follows: vomiting 0.067, fever 0.078, rash 0.024, itching 0.039, headache 0.072. Risk differences were adjusted for age, or presented stratified by age group when there was a signification interaction with age.

各结局指标的组内相关系数（Intraclass correlation coefficients）如下：呕吐0.067、发热0.078、皮疹0.024、瘙痒0.039、头痛0.072。风险差已针对年龄因素进行校正；若与年龄存在具有统计学意义的交互作用，则按年龄组分层呈现。
