Other related information

1. A systematic search of the literature will be conducted according to PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analysis) Statement. We will search the following electrical databases; the Cochrane Library; PubMed. Additionally, we will also search the other resources; the World Health Organization International Clinical Trials Platform Search Portal (ICTRP) and ClinicalTrials.gov.

2. To assess the risk of bias, we will use the Risk of Bias 2 tool for RCTs. Two reviewers will independently screen the full text of each study and decide whether the studies met the inclusion criteria. Any disagreement will be resolved by discussion or consulting the third reviewer.

3. Meta-analysis will be performed using statistical software, such as Review Manager 5.3.5, R, and STATA.

4. Sensitivity analysis and subgroup analysis will be performed as needed based on the results of the adopted literature.

5. SOF tables will be created for the following outcomes.
1. Exacerbation requiring hospitalization
2. Severe exacerbations (requiring ED visits or systemic steroids, or both)
3. Serious adverse events (including mortality)
4. Asthma symptoms (symptom scales, Asthma Control Questionnaire, Asthma quality of life (AQLQ) )
5. Rescue medication (puffs/day)
6. Respiratory function (morning PEF, evening PEF, FEV1)
7. Bronchial hyperresponsiveness (BHR).
8. Minimum oral corticosteroid dose
