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.
