Fig. 6: Event-free survival by NLR category at last available assessment in PROUD-PV/CONTINUATION-PV.

Association between NLR at last available assessment and the occurrence of risk events (thromboembolic events, disease progression to myelofibrosis or acute myeloid leukemia, or death) shown by time-to-first-risk-event analysis in subgroups based on NLR over or under the threshold of 4.3 (the median level recorded at baseline).
