Predicting unplanned extubation risk in patients with endoscopic nasobiliary drainage

Figure 4 Clinical risk assessment nomogram. This is a medical risk assessment nomogram that calculates risk probability based on multiple clinical variables including age, smoking history, fasting time, catheter duration, serum albumin levels, and consciousness changes. The patient’s total score of 159 points corresponds to a high-risk threshold of approximately 0.8 (80%) probability for an adverse medical outcome. Orange represents the high-risk cutoff value.
