A researcher summarizes her results of research into the use

A researcher summarizes her results of research into the use of a specific type of inhaler for asthma sufferers as follows: ‘predictors significantly favored inhaler use (adjusted R²= .38; p = .015). Inhaler A was the strongest predictor of improved breathing ( = .39; p = .001) followed by inhaler B ( = .28; p = .0015)’. What statement could be made about the findings noted in these results?
