The thrombodynamic ratio as a predictor of 28-day mortality in sepsis patients

•Thrombodynamic ratio reflects the varying change of haemostasis in sepsis.•Lower thrombodynamic ratio, more likely to have organ impairments.•Thrombodynamic ratio significantly predicts 28-day mortality in patients with sepsis.•Thrombodynamic ratio improves the discrimination and calibration performance of clinical prediction models.
