1: Clinical score for assessing the intensity of asthma attacks in
children (modified Wood-Downes score) (22).
Analysis:
The data were analyzed using the SPSS software, version 16.0.
Categorical variables were expressed as a percentage and compared using
the Chi-square test or relative risk. Continuous variables with normal
distribution were expressed using means with the respective standard
deviation and compared using Student’s t test. Continuous
variables without normal distribution were expressed using the median
with the respective interquartile range (IQ 25% -75%) and compared
using the Mann-Whitney or Kruskal-Wallis tests. Correlation tests were
also performed (Pearson’s correlation coefficient and determination
coefficient).
