MOESM5 of Effects of Plasmodium falciparum infection on umbilical artery resistance and intrafetal blood flow distribution: a Doppler ultrasound study from Papua New Guinea

Additional file 5. Associations of recent malaria infection with Doppler indices. A total of 533 malaria tests preceded the Doppler scan by no more than 6Â weeks and were thus considered â recentâ . In this category, 17 were positive for P. falciparum with either method (13 by qPCR; 11 by LM) and two were positive for P. vivax, by qPCR. Of these, seven infections were sub-microscopic. These data are not shown in the main text as the numbers of recent malaria episodes were too low to confidently perform statistical analyses.

附加文件5：近期疟疾感染与多普勒指数（Doppler indices）的关联分析。共计533份采样时间不晚于多普勒扫描前6周的疟疾检测样本，因此被归为“近期”检测样本。在该类别中，17份样本经任意一种检测方法检出恶性疟原虫（Plasmodium falciparum），其中13份经实时荧光定量PCR（qPCR）检出，11份经光学显微镜（Light Microscopy，LM）检出；另有2份经qPCR检出间日疟原虫（Plasmodium vivax）。其中7例感染为亚显微感染。由于近期疟疾感染病例数过少，无法开展具有统计学可信度的分析，因此本数据未在正文中展示。
