                 Background
                 Previous studies showed that health-related quality of life (HRQL) significantly
                 improved after the food challenge, with greater improvements in HRQL after
                 a negative outcome than after a positive outcome. It is currently unknown
                 whether this also occurs in patients undergoing DBPCFCs with cashew nut in
                 the context of a clinical trial.                                     Conclusion
                                                                                      This study showed no difference in

                 Results: In total, 112 children (67 boys, median age of 9 years) were includ-
                 ed. The children, teenagers and parents of the children completed 143 sets
                 of questionnaires in total. There were no significant differences in baseline
                 total and domain scores compared to the follow-up scores in the FAQLQ-CF,
                 FAQLQ-TF and FAQLQ-PF. In children, the delta FAIM score in the negative
                 DBPCFC tested group was significantly better than the delta FAIM score in the
                 positive challenged group (p = 0.026). There were no significant differences
                 in the changes in the scores of the FAQLQ-CF and FAQLQ-PF in the children
                 with a positive challenge outcome, compared to the children with a negative
                 challenge result. However, there was a significant difference in the change in
                 score between the latter groups in the domain ‘accidental exposure’ of the
                 FAQLQ-TF (p = 0.049).
