When analyzing the correlation between cytokines and pulmonary function, IL‐10 showed negative associations with FEV1 (ρ = –0.251; p = 0.025) and FVC (ρ = –0.265; p = 0.018), suggesting that higher IL‐10 concentrations may be associated with reduced pulmonary function in children and adolescents with asthma. Here, IL10 is linked to asthma.
