Abbreviations: FEV1 = forced expiratory flow in one second; PEF = peak expiratory flow; ACQ = asthma control questionnaire; FeNO = fractional exhaled nitric oxide; ↑ = significant increase as compared to the control group; ↓ = significant decrease as compared to the control group; = = no change as compared to the control group; * = Jadad score was calculated to assess the methodological quality of the RCTs. The calculation of the Jadad score can be found in Supplemental Table S1; 1 = exhaled H2O2. Quantitative data showing the within-group changes is presented in Supplemental Tables S3–S7.
