What was measured
The Work Productivity and Activity Impairment Questionnaire: Specific Health Problem (WPAI:SHP) is a six item questionnaire which intended to measure work and activity impairment associated with polycythemia vera. WPAI consisted of 6 questions (Q1=Employment status; Q2=Hours absent from work due to the polycythemia vera; Q3=Hours absent from work due to other reasons; Q4=Hours actually worked; Q5=Impact of the polycythemia vera on productivity while working; Q6=Impact of the polycythemia vera on productivity while doing regular daily activities other than work). Higher WPAI scores indicated greater activity impairment. Scores were multiplied by 100 to express in percentages.
Percent work time missed due to problem (past 7 days) =Q2/(Q2+Q4) Percent impairment while working due to problem (past 7 days): Q5/10 Percent overall work impairment due to problem (past 7 says): Q2/(Q2+Q4)+\[(1 Q2/(Q2+Q4))x(Q5/10)\] Percent activity impairment due to problem (past 7 says): Q6/10
Analysis population: Full Analysis Set (FAS) included all participants to whom study treatment was assigned by randomization and had valid measurements for the outcome measure. Data after crossover for participants randomized to BAT are reported as separate outcome measure.
Groups in this outcome
Ruxolitinib
Ruxolitinib at a starting dose of 10 mg twice a day (bid). Dose was adjusted based on efficacy and safety parameters up to a maximum dose of 25 mg bid
Best Available Therapy (BAT)
Best Available Therapy as selected by the investigator from: Hydroxyurea, Pegylated-Interferon (IFN/PEG-IFN), pipobroman, anagrelide, IMIDs, or observation. Participants randomized to BAT who did not respond by Week 28 were eligible to crossover and start treatment with ruxolitinib
Group identifiers and denominators belong to this outcome only. They may differ in another outcome or in safety reporting.
