Association between semi-quantitative microbial load and respiratory symptoms among Thai military recruits: a prospective cohort study

Table 3 Frequency of co-detections with selected organism pairs among acute samples. Acute specimens were collected from individuals who developed upper respiratory tract infection during follow-up (n = 145)

^aPercentages indicate proportion of acute samples where each microbe was identified
^bPercentages indicate proportion of acute samples where each microbe pair was co-detected
^cp-value computed by χ²- or Fisher’s exact (*) test, indicating that co-detection of each of the listed microbe pairs occurred more frequently than expected by chance
