Total Symptom Score (TSS) by Smoking Status and MPN subtype. Comparison of TSS between current/formers smokers and never smokers by MPN subtype. The TSS was calculated for all respondents completing at least six of the 10 MPN-10 items. MPN: Philadelphia-negative chronic myeloproliferative neoplasms; ET: essential thrombocythemia; PV: polycythemia vera; MF: myelofibrosis. No significant mean differences were observed, though p = 0.07 for All MPN and p = 0.06 for PV
