Associations between cord blood YKL-40 levels and asthma at 6 years. CI: confidence interval; log: logarithmic; OR: odds ratio. Data is given as OR (with 95 % CI) for asthma at 6 years for 4 different categories of cord blood YKL-40 levels above detection limit. YKL-40 non-detects (not shown) served as reference. Data are derived from n = 135 children with n = 15 with asthma diagnosis. The combined P–value for trend for the adjusted OR was (Ptrend = 0.169)
