(+) positive impact of the CHI application on outcome; (−) negative impact of the CHI application on outcome; (0) no impact or not a significant of the CHI application on outcome

while the CHI application showed positive impact in knowledge scores across groups, the change in scores was most significant in these two groups using the application DPI=dry powder inhaler; MDI=metered dose inhaler
