Fig. 1 — Data on country income derived from World Bank data. The graphs show the results of a global online survey of haemodialysis units, which was aimed at determining patterns and access to resources associated with haemodialysis care during the COVID-19 pandemic. As shown, LICs had the greatest shortage of personal protective equipment (PPE) at the peak of the pandemic (a) and the greatest use of PPE beyond manufacturer’s shelf life (b), the latter representing a need to continue using out-of-date PPE owing to a shortage of supply. HIC, high-income countries; LIC, low-income countries; LMIC, lower-middle-income countries; UMIC, upper-middle-income countries.
