Statistical assessment
Demographic data were analyzed using descriptive statistics. A
comparison of skin test positivity in relation with severity of HSRs,
time lapse from LOCM exposure, and according to the side chain were
performed using Pearson’s chi-squared test or Fisher’s exact test.
Statistical analyses were performed using IBM SPSS version 23.0 (IBM,
Corp., Armonk, NY, USA), and results with P ≤ 0.05 were
considered statistically significant.
