Statistical analysis
Predictors of developing severe FPIES reactions and multiple trigger
FPIES were explored using logistic regression with odds ratio (OR)
estimates and 95% confidence intervals (CI) presented. Age at
resolution of FPIES was described using the Kaplan-Meier method and
predictors tested using proportional hazards regression models, with
hazard ratios (HR) and CI presented. Pearson correlation coefficients
were used to examine correlations among individual food triggers.
Analysis was performed using SAS software version 9.4 (SAS Institute
Inc., Cary, NC) and GraphPad Prism 8 (GraphPad Software, La Jolla,
Calif).
