Study Notes
Asthma Reliever Therapy Comparison
-
Study Objective: To compare short-acting beta agonists (SABA) alone with SABA combined with inhaled corticosteroids (ICS) and with a fast-acting, long-acting beta agonist (formoterol) combined with ICS for asthma treatment.
-
Data Sources: MEDLINE, Embase, and CENTRAL databases were searched from 2020 to 2024, encompassing all languages.
-
Study Selection: Randomized clinical trials evaluating SABA alone, ICS+formoterol combination, and ICS+SABA combination therapies were selected.
-
Participants: 50,496 adult and pediatric patients; average age 41 years; 40% male.
-
Key Outcomes: Asthma symptom control (using a 5-item questionnaire), asthma quality of life (using a questionnaire), risk of severe exacerbations, and risk of serious adverse events.
Treatment Comparison Results
-
ICS-Containing Therapies (Compared to SABA Alone):
- Associated with fewer severe exacerbations (highly certain evidence)
- ICS-formoterol: Risk Ratio (RR) 0.65 (95% Confidence Interval [CI] 0.60-0.72); Risk Difference (RD) -10.3% (95% CI -11.8% to -8.3%)
- ICS-SABA: RR 0.84 (95% CI 0.73-0.95); RD -4.7% (95% CI -8.0% to -1.5%)
- Associated with improved asthma control (highly certain evidence)
- ICS-formoterol: MID improvement in total score RR 1.07 (95% CI 1.04–1.10); RD 4.1% (95% CI 2.3%–5.9%)
- ICS-SABA: RR 1.09 (95% CI 1.03–1.15); RD 5.4% (95% CI 1.8%–8.5%)
- Associated with fewer severe exacerbations (highly certain evidence)
-
ICS-Formoterol vs. ICS-SABA (Indirect Comparison):
- Associated with fewer severe exacerbations (moderate certainty). RR 0.78 (95% CI 0.66–0.92); RD -5.5% (95% CI -8.4% to -2.0%).
-
Serious Adverse Events:
- ICS-formoterol: Not associated with an increased risk (high certainty). RD, -0.6% (95% CI -1.3% to 0%)
- ICS-SABA: Not associated with an increased risk (moderate certainty). RD 0% (95% CI -1.1% to 1.2%).
