Risk Factors for 30-Day Prognosis of Hemorrhagic Fever with Renal Syndrome in the Dali Region, China

PT, FT3, WBC levels, and LAR values are risk factors for 30-day mortality in patients with HFRS. Moreover, we have, for the first time, identified a close association between FT3 and LAR and the prognosis of HFRS. The developed nomogram demonstrates favorable predictive performance and can serve as an intuitive quantitative tool for the early identification of high-risk patients, thereby guiding clinical intervention strategies.
