2.4. Measurements and statistical analysis
Distribution of age, sex, initial clinical symptoms and on admission
vital signs were compared between the two groups. Mortality rate,
duration of hospitalization, mechanical ventilation and ICU length of
stay were also evaluated.
The results were analyzed using SPSS v.25.0 software. Chi-square tests
were performed to evaluate the difference in qualitative data.
Shapiro-Wilk test was performed to assess the normality of data
distribution. To compare the differences in the quantitative variables
of groups, the independent t-test and One-way analysis of variance
(ANOVA) was carried out. Values with p<0.05 were considered
statistically significant.
