Evaluation of erythrocytapheresis compared to phlebotomy in polycythaemia vera patients.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
introductionPolycythaemia vera patients can present with arterial or venous vascular occlusive events such as thrombosis or cardiovascular disease; disease-related symptoms may significantly impact on the quality of life. The aim of this study was to evaluate the efficacy and safety of erythrocytapheresis compared to phlebotomy in the treatment of polycythaemia patients.
methodsThis study reports the findings of a retrospective analysis of 40 polycythaemia vera patients diagnosed according to published guidelines and treated either with erythrocytapheresis or phlebotomy over a four-year period. The goal of treatment was to reduce blood volume and red blood cell count to near normal levels as both of which may attenuate the symptoms and complications associated with polycythaemia. Patients were treated by applying a mathematical model.
resultsUsing the model, 28 erythrocytapheresis procedures were performed. Blood laboratory values (red blood cell count, haemoglobin count and haematocrit level) were significantly reduced in patients treated with erythrocytapheresis. Moreover, among treated patients, erythrocytapheresis resulted in less work absenteeism and reduced costs due to lost production, with a lower overall procedure cost in comparison to phlebotomy.
conclusionThis model can assist in selecting the proper treatment modality for individual patients. Especially for those with high blood volumes and high achievable haematocrit levels (delta), erythrocytapheresis offers a more efficient method in red blood cell depletion compared to phlebotomy thereby, potentially reducing the number of treatment procedures required for the induction of polycythaemia vera patients as well as the interval between procedures during the maintenance phase.
