Severe versus common COVID-19: an early warning nomogram model


Figure 1. Risk prewarning nomogram for severe type patients. Each patient’s variables could be located on the corresponding variable axis. The point of each variable could be determined by vertically referring to the top point line. By summing up the total points of each corresponding variables, total point was calculated, and risk of disease progression was determined by reading against the risk axis.
