Footpad swelling in the mouse model of cross-reactive metal allergy. Footpad swelling was measured at various time points. The Cr-Pd, Ni-Pd, and Saline-Pd groups were analyzed at 1, 3, and 7 days after the third challenge. Bars and error bars indicate the mean ± SD. Statistical significance was tested by the Dunn’s test (* p < 0.05, ** p < 0.01).
