Asthmatic/wheezing phenotypes in preschool children: Influential factors, health care and urban-rural differences

Overall, low numbers of allergy tests among children with physician's diagnoses highlight a discrepancy between common practice and current knowledge and guidelines. Residential differences in health care might encourage further research and interventions strategies.
