Figures are Kappa statistics (p values) where represent the level of agreement between allergen sensitization tests having taken into account any agreement that is expected by chance. Results of 0.61–0.99 signify excellent agreement, 0.41–0.60 signifies moderate agreement and 0.01–0.4 signifies only slight to fair agreement [18]
