Bold letters indicate a co-sensitization rate of more than 70%. “n” represents the number of patients with positive SPT reaction. The percentage of co-sensitization of weed and grass pollen species was calculated by dividing the number of patients with a positive SPT reaction to pollen Species 2 by the number of patients sensitized to pollen Species 1, expressed as a percentage.
