Hs‐CRP values averaged 1.1 (95% CI, 0.26–16.23) μg/ml, not dissimilar from 50 age‐ and sex‐matched non‐PV patients on aspirin prophylaxis25 (2.3 [95% CI, 0.6–4.8] μg/ml, p = 0.10), and did not correlate with any of the variables under study (Table S2). This evidence concerns the gene MAP3K14 and acquired polycythemia vera.
