Fig. 4From: Viral loads in nasopharyngeal aspirates and tracheal aspirates among children hospitalized with invasive ventilation for human adenovirus pneumoniaViral loads (median [IQR]) in NPA and TA samples collected from 94 patients at days 3–30 after disease onset. The data after day 30 of onset were not due to small numbers of paired samples. Continuous data for > 10 paired samples were analysed by 2-tailed paired Mann–Whitney U tests. All P values indicate significant differences. Abbreviations: n, number of pairs of samples; NPA, nasopharyngeal aspirate; TA, tracheal aspirateBack to article page
