Evaluation of the serum Hsp70 (ng/ml) from healthy volunteers and bronchial asthma patients. (A) Comparison of circulating Hsp70 between healthy donors (n = 78) and asthmatic patients (n = 78). (B) Comparison of circulating Hsp70 between healthy volunteers and asthmatic patients of different severity. (C) Correlations of Hsp70 levels by smoking (n = 42). (D) Correlations of Hsp70 levels by BMI (body mass index) (n = 73). (E) Correlation of serum Hsp70 level by patients’ gender (n = 78). (F) Correlations of Hsp70 levels in different age groups of patients (n = 78). (G) Correlations of Hsp70 levels by BA phenotype (n = 56). (H) Serum Hsp70 content in eosinophilic and non-eosinophilic BA patients. To compare between the groups the Wilcoxon signed rank test was employed. Data is presented as M (mean) ± SE (standard error). Significant differences identified by the Wilcoxon signed rank test are shown as *p < 0.05, ** p < 0.01, ***p < 0.001, ****p < 0.0001.
