Comparative statistics
In the statistical comparison, there was found a significant difference
in the oxygenation index at admission presented by lactated vs.
non-lactated patients (p 0.002), as well as the presence of crackles p =
0.029 (95% CI 0.502-0.095) and wheezing p = 0.043 (95% CI
0.522-0.980). (Table 3)
The comparative analysis of the medians of these averages was performed,
finding a statistically significant difference between the levels of
specific IgA and the personal history of repetitive respiratory tract
infections (defined according to the Mexican CPG as more than 3
respiratory infections per year) (p = 0.018). Differences were also
found in symptoms such as: dry cough (figure 2), presence of severity
signs such as thoracoabdominal dissociation (figure 3), (p = 0.043, p =
0.044 respectively). (Table 4)
