Table 5 Correlations between CHQ-PF28 scale scores and allergy-associated parameters. Spearman correlation coefficients with statistical significance between PhS, PsS, PE, PT, FA and FC1 and number of offending food items, food-induced reactions, allergic diseases, additional allergies/hypersensitivities and years of age.

  1. 1 CHQ-PF28 health scales: PhS = Physical Summary score; PsS = Psychosocial Summary score; PE = Parental impact-Emotional; PT = Parental impact-Time; FA = Family impact-Activities; FC = Family impact-Cohesion [28].
  2. 2 Positive correlation coefficients, shown in italics, indicate a positive relationship, i.e. the higher the number of offending food items/types of food reactions/years of age, the higher the HRQL scores.
