Cohort characteristics associated with symptomatic DENV illness.

*Refers to first-detected DENV infections in the cohort that occurred during the active surveillance period each year (June 1–November 1) and had neutralizing antibody data available**Statistical tests considered the association between variables of interest and the occurrence of symptomatic versus asymptomatic infection. p-values were obtained using the Pearson chi-square test for categorical variables, with α = 0.05 as the level of significance. ‘Missing’ categories were not included in statistical comparisons.

本数据集特指队列研究人群中，于每年主动监测周期（6月1日至11月1日）内首次检出的登革病毒（DENV）感染病例，且该类感染均具备可获取的中和抗体检测数据。本研究通过统计学检验分析目标变量与症状性感染、无症状感染发生情况之间的关联。针对分类变量，采用皮尔逊卡方（Pearson chi-square）检验计算P值，以α=0.05作为显著性检验水准，统计比较过程未纳入'缺失'类别。
