Eczema is linked to an increased risk of asthma.

Is it true that eczema is linked to an increased risk of asthma?

Partly. Several placed studies show eczema and asthma co-occurring or sharing risk factors, but they are cross-sectional or comorbidity reports in single populations, and one cohort found the asthma association absent among children with eczema. No item establishes that eczema itself raises the risk of developing asthma.
