To learn more about whether SHS exposure was being assessed in COVID-19 studies, we contacted researchers who had published COVID-19-related work.We contacted corresponding authors of peer-reviewed scientific articles published between February and April of 2020 identified by PubMed systematic searches using ‘COVID OR Coronavirus AND Risk Factors’ and similar terms. Abstracts were reviewed and papers included if they had data from patients with COVID-19 and risk factors. We … ER -
