Table 3. Associations between the absolute concentration of indoor microbial species and allergic rhinitis in junior high school, Terengganu. Odds ratio and 95% confidence interval (CI) were calculated by 3-level hierarchic linear regression models adjusted for gender, smoking and parental asthma. The regression was conducted for species presented in at least 10 classrooms with mean relative abundance > 0.1%. In total, 170 bacterial and 89 fungal species were analyzed. Only associations with p < 0.005 are presented in the table. GM stands for geometric mean. The false discovery rate (FDR) was calculated by Benjamini-Hochberg (BH) procedure.
