A Cost Effectiveness Analysis of Rivaroxaban Compared to Warfarin for Deep Vein Thrombosis (DVT) Treatment in Ethiopia.
Article in ClinicoEconomics and outcomes research : CEOR, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers, 1 of them a synthesis that pooled it.
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
backgroundDeep vein thrombosis and pulmonary embolism are known by the collective name venous thromboembolism. Deep vein thrombosis is the third most common cardiovascular disorder in the world. The disease is also prevalent in Africa including Ethiopia, besides lack of studies that show epidemiology of the disease.
objectiveTo assess cost effectiveness of rivaroxaban compared to warfarin-based therapy for deep vein thrombosis patients in Ethiopia.
methodsA Markov model was built to compare cost and effectiveness of rivaroxaban 15mg bid for three weeks and 20mg per day for the rest to adjusted dose of warfarin for one year using a restricted societal perspective. The population in this analysis was a hypothetical cohort of deep vein thrombosis patients 40 years old with no contraindication, comorbidity and concomitant therapy. The patients were followed yearly for 24 years up to their average life expectancy.
resultsRivaroxaban therapy resulted in higher quality adjusted life years with a value of 16.78, while warfarin-based treatment resulted in 16.34 quality adjusted life years. Total lifetime costs were $988.58 for rivaroxaban and $932.92 for unfractionated heparin/warfarin. Therefore, rivaroxaban resulted in a gain of 0.443 quality adjusted life years at an additional cost of $55.661. The incremental cost effectiveness ratios for rivaroxaban compared with warfarin was $125.683 per quality adjusted life year saved which is less than willingness to pay threshold of $783 per quality adjusted life year saved. Warfarin resulted in a net monetary benefit of $11,859.72, while that of rivaroxaban is $12,150.82, meaning rivaroxaban is cost-effective. Sensitivity analyses found that the model was sensitive to utility of no deep vein thrombosis, effectiveness of rivaroxaban and cost of rivaroxaban respectively.
conclusionThis study showed that rivaroxaban is a cost effective alternative and substituting rivaroxaban for warfarin is acceptable to willingness to pay threshold.
