A formula that predicts Covid-19 patients' chances of surviving has been developed by British researchers. It will save lives by personalising therapy based on their profile, say scientists.
The 'risk identification tool' divides those admitted to hospital into four distinct groups - ranging from low to very high.
In the lowest category, one in every hundred is at risk of dying - compared to ten in the 'intermediate'. This soars to 31 and 62 in a hundred for 'high' and 'very high' risk patients, respectively.
Senior author Professor Ewen Harrison, of Edinburgh University, said: "As doctors, we want to identify groups of patients most at risk of dying from Covid-19. "If we can do that at the front door of the hospital, then treatment can be
