Cost-utility analysis of valsartan, enalapril, and candesartan in patients with heart failure in Iran.
Article in Health economics review, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
backgroundToday, heart failure is one of the leading causes of death and disability in most developed and developing countries. By 2030, more than 23.3 million people are projected to die of cardiovascular diseases each year, and the prevalence of heart failure is expected to increase by 25%. One of the preventive interventions is pharmacological interventions which can be used to reduce the complications of cardiovascular diseases such as heart failure. One of the most important pharmacological interventions in patients with heart failure is the use of antihypertensive drugs such as candesartan, enalapril, and valsartan. This study aimed to compare the cost-utility of candesartan, enalapril, and valsartan in patients with heart failure using the Markov model in Iran in 2020.
methodsIn the present study, a four-state Markov model was designed to compare the cost-utility of candesartan, enalapril, and valsartan for a hypothetical cohort of 10,000 heart failure patients older than 24 years. The payers' perspective was used to calculate the costs. The Markov states included outpatients with heart failure, patients with heart failure admitted to general hospital wards, patients with heart failure admitted to the intensive care units (ICUs), and death. The effectiveness measure in this study was the quality-adjusted life years (QALYs). The one-way and probabilistic sensitivity analyses were used to determine the robustness of the results. The TreeAge Pro 2011 software was used for data analysis.
resultsThe results showed that the average expected costs and QALYs were 119645.45 USD and 16.15 for valsartan, 113,019.68 USD and 15.16 for enalapril, and 113,093.37 USD and 15.06 for candesartan, respectively. Candesartan was recognized as the dominated option. Because the calculated incremental cost-effectiveness ratio (ICER) value (6,692.69 USD) was less than the threshold value (7,256 USD), valsartan was cost-effective compared to enalapril. The results of the cost-effectiveness acceptability curve showed that at the threshold of 7,256 USD, valsartan had a 60% chance of being cost-effective compared to enalapril. The results of one-way and probabilistic sensitivity analyses confirmed the robustness of the results. Moreover, the results showed that ICU (1,112 USD) had the highest cost among cost items.
conclusionAccording to the results, it is recommended that health policymakers consider the use of valsartan by cardiologists when designing clinical guidelines for the treatment of patients with heart failure.
