Relationship between HRV viral load and severity of asthma exacerbations among inpatients. A: HRV total viral load among the three groups shows no significant difference. B: HRV‐A viral load in severe group was significantly higher than in the mild and moderate groups (P < 0.001 and P = 0.022). C: HRV‐C viral load the among three groups shows no significant difference. D: HRV‐A and HRV‐B viral load were significantly higher than HRV‐C regardless of the severity (P < 0.001 and P = 0.014). E: In the severe group, HRV‐A viral load was significantly higher than HRV‐C (P < 0.0001). The comparison of viral load was conducted by nonparametric Mann‐Whitney U‐test
