Nasopharyngeal colonisation of S. pneumoniae and S. aureus in parents of unvaccinated children and of children receiving a 2-dose or 2+1-dose PCV7-schedule.

Parents of twins (n = 15 pairs) were excluded. Analyses were performed with Chi-square or 2-sided Fisher Exact test where appropriate.afor the control group: n = 305; for the 2-dose group: n = 318; for the 2+1-dose group: n = 328.bfor the control group: n = 296; for the 2-dose group: n = 309; for the 2+1-dose group: n = 321.

本研究排除了15对双胞胎的家长研究对象。适宜条件下采用卡方检验（Chi-square test）或双侧Fisher精确检验（Fisher Exact test）开展统计分析。注a：对照组受试者例数n=305，两剂次组n=318，2+1剂次组n=328。注b：对照组受试者例数n=296，两剂次组n=309，2+1剂次组n=321。
