Pilot study: assessing the clinical diagnosis of allergy in atopic children using a microarray assay in addition to skin prick testing and serum specific IgE

Table 1 Agreement between the tests based on sensitization

Cat	0.53 (0.007)	0.86 (<0.001)	0.56 (0.003)

Timothy grass pollen	0.28 (0.063)	0.73 (<0.001)	0.44 (0.005)
House dust mite	0.73 (<0.001)	0.58 (0.002)	0.92 (<0.001)
Alternaria mould	−0.25 (0.855)	0.06 (0.390)	0.70 (<0.001)

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]
