Assessment of asthma control
The GINA guidelines1 recommend to evaluate daytime
symptoms, nocturnal symptoms, need for reliever therapy, limitation of
physical activities, lung function and assessment of future risk in
order to determine control status. Based on the parameters defined by
the GINA guidelines, patients were grouped as having
“well-controlled”, “partly controlled” and “uncontrolled” asthma
for the previous 4 weeks. “Partly controlled” and “uncontrolled”
group were collected as “not well-controlled”. So, the analyses were
performed for these two groups of “well-controlled” and “not
well-controlled” asthma.6
