Graph 1: Mean 30-minute urinary concentration of salbutamol
concerning total correct steps
The concentration of 30-minute urinary salbutamol concentration
concerning exacerbation, antibiotic, and OCS use was shown in Table 1.
On assessing the salbutamol concentration concerning episodes of
exacerbation, the mean urinary concentration of salbutamol was found to
be 5.3 µg/ml, 4.5 µg/ml, 3.1 µg/ml, 3.2 µg/ml, 3.3 µg/ml, and 0.5 µg/ml
among cases with exacerbation of zero episodes, one, two, three, four,
and six episodes of exacerbations, respectively. The mean difference in
concentration of salbutamol and exacerbations in the past year was found
to be statistically insignificant. (p=0.192)
The mean concentration of salbutamol was found to be 5.3 µg/ml, 3.3
µg/ml, 3.3 µg/ml, 3.5 µg/ml, 1.7 µg/ml, and 0.5 µg/ml among cases with
antibiotic use of zero courses (not taken antibiotics), one, two, three,
four and five courses of antibiotic use, respectively. On assessing the
difference in the mean concentration of salbutamol and a short course of
OCS use, the mean concentration of salbutamol was found to be 5.0 µg/ml,
4.3 µg/ml, 3.4 µg/ml, 3.1 µg/ml, and 1.3 µg/ml among cases with short
course OCS use of zero courses (not taken OCS), one, two, three and four
courses of antibiotic use, respectively.
