borderline significantP = .057
A borderline significant benefit on PFS was observed for early interruption (HR = 0.61, P = .057), while late interruption (HR = 0.60, P = .183) and interruptions based on duration (≤2 cycles: HR = 0.46, P = .138; >2 cycles: HR = 0.67, P = .096) were not statistically significant.
