Early chemotherapy after endoscopic retrograde cholangiopancreatography and survival in advanced pancreatic cancer with biliary obstruction

Figure 4 Robustness and sensitivity forest plot. Forest plot showing hazard ratios and 95%CIs for the association between chemotherapy initiation within 30 days after endoscopic retrograde cholangiopancreatography and landmark overall survival across the primary weighted Cox model and prespecified sensitivity analyses, including doubly robust adjustment and common-support restriction. IPTW: Inverse probability of treatment weights; HR: Hazard ratio; SMD: Standardized mean difference; ESS: Effective sample size; DR: Doubly robust; TBil: Total bilirubin; CRP: C-reactive protein; CS: Common-support.
