A history of asthma lasting > 20 years was identified as an independent risk factor for FAO in geriatric asthmatics (OR = 8.578, 95% CI = 1.610-45.741, <i>p</i> < 0.05).<h4>Conclusions</h4>Geriatric asthmatics exhibit more comorbidities, poorer lung function, higher neutrophil ratios, and elevated CRP levels. Here, CRP is linked to asthma.
