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).
