3.3 Statistical Analysis
Mean and standard deviation for continuous variables as well as numbers
and percentages for categorical variables were used to describe the
baseline characteristics of patients with cardiac AEs after exposed to
TKIs. The reporting odds ratio (ROR), the proportional reporting ratio
(PRR), the Bayesian confidence propagation neural network (BCPNN) and
the multi-item gamma Poisson shrinker (MGPS) algorithms were used to
identify the association of drugs and AEs [23]. AEs were considered
statistically significant when at least 1 of the above 4 criteria was
met(Table 2).
