Impact of hospital bed availability per country on STEMI hospitalizations during COVID-19 pandemic.

Meta-regression of number of hospital beds/1000 inhabitants (X-axis) vs incidence rate ratio (IRR) of STEMI hospitalizations in each country during peak COVID-19 pandemic, relative to reference period (Y-axis). Circles represent individual studies; diameter is proportional to the inverse of the variance of the IRRs (p < 0.017). See Table 2 for details.

Note the inverse relationship between bed availability and STEMI hospitalization, which stayed around historical levels in countries with greater bed availability, while it sharply decreased along with bed availability, suggesting an important role of health organization.
