Statistical analysis
Statistical analysis was performed using graph pad prism version 9 and
non-parametric statistical tests were used. The differences in clinical
features between those who had sensitization to alpha-gal compared to
others during the episode of anaphylaxis was expressed as the odds ratio
(OR), which was obtained from standard contingency table analysis by
Haldane’s modification of Woolf’s method. The Fisher’s exact test was
used to determine the p value.
