Statistics
Data were analyzed using SPSS, version 25 (SPSS Inc; Chicago, Illinois).
Demographic factors, organ systems and medical diagnoses were summarized
with percentage breakdown. For comparison of difference between two
sub-groups, independent samples t-test was used when normal distribution
was assumed, otherwise, a Mann-Whitney test was used. The findings of
the CFE were compared with VFSS data using Fisher’s exact test or Chi
square test. Multivariate analysis for medical diagnoses was conducted
using a logistic regression model. To determine the positive and
negative predicted value of the CFE compared to VFSS, a fourfold table
with Crosstabulation was used. Interrater agreement was measured using
Cohen’s Kappa coefficient. The McNemar Chi2 test was
used to assess the change in feeding route following VFSS.
