Statistical analysis
Continuous data were described as mean ± SD, while median (interquartile
range) was used for abnormal data. Categorical data was described with a
number (percentage). All tests were 2-sided, and a P-value <
.05 was considered statistically significant. The statistical analysis
was performed using SPSS version 25.0 for Windows (IBM Software, Inc,
Armonk, NY).
