Nomogram for predicting respiratory failure development in SFTS patients with pneumonia. To use, locate the patient’s neurological manifestations and draw a line straight upward to the “Points” axis to determine the score associated with neurological manifestations. Repeat the process for nosocomial infections, AKI stage 2 or 3, SIRS, albumin, and CKMB, and sum the scores together and locate this total score on the“Total Points” axis. Draw a line straight down to determine the probability of respiratory failure development.
