Meta-analysis is the best choice as it allows for the combination of results from multiple studies, providing a more comprehensive overview of the effects of the drug on childhood asthma treatment. It also increases the statistical power of the analysis, allowing for more accurate conclusions to be drawn. Patient surveys and observational studies are not as reliable as they are subject to bias and confounding variables. A standardized t-test would only be appropriate for comparing the means of two groups, whereas a meta-analysis involves multiple studies.
