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

Figure 6 Dynamic bilirubin trajectory and day 7-30 chemotherapy accessibility. Cumulative incidence function curves for chemotherapy initiation during days 7-30 after endoscopic retrograde cholangiopancreatography according to dynamic bilirubin trajectory groups defined by baseline and day-7 total bilirubin relative to the 171 μmol/L threshold. Death before chemotherapy initiation was treated as a competing event. The lower panel shows the day-30 cumulative incidence and the number of patients and chemotherapy events in each group. CIF: Cumulative incidence function; sHR: Subdistribution hazard ratio; ERCP: Endoscopic retrograde cholangiopancreatography.
