1 · What the graph read from 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.

2 · The registry

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

BACKGROUND AND

objectiveCurrent Australian cardiovascular disease (CVD) prevention guidelines calculate 5-year CVD risk and recommend treatment when risk crosses specific thresholds. This may leave risk factors untreated for people with a low short-term (i.e. 5 years), but high long-term (i.e. lifetime), risk of CVD. We aimed to evaluate the cost effectiveness of intervention for risk factor control at age 40 years (regardless of calculated risk) compared to intervention for risk factor control at the age recommended by contemporary Australian CVD prevention guidelines (when the 5-year CVD risk reaches 10%) across a range of individual risk factor profiles.

methodsWe used a causal microsimulation model populated with 108 different risk factor profiles, each replicated 10,000 times. Model data were derived from the UK Biobank study and published sources. The primary causal relationships factored in were those of low-density lipoprotein-cholesterol and systolic blood pressure with CVD (defined as myocardial infarction or stroke). The model simulated the ageing of individuals from 40 to 85 years. We calculated years of life lived, quality-adjusted life-years gained, incremental healthcare costs and the incremental cost-effectiveness ratio when low-density lipoprotein-cholesterol and blood pressure were controlled from age 40 years compared to initiation of treatment as recommended by Australian guidelines. The main side effect in the model was an increased risk of type 2 diabetes mellitus from statin use. The trade-off between reduced CVD and increased type 2 diabetes was summarised via quality-adjust life-years. Incremental cost-effectiveness ratios were compared to the Australian willingness-to-pay threshold of AU$28,000 per quality-adjust life-year gained. We adopted a healthcare perspective (2022 AUD) and discounted results at 3% annually.

resultsAn earlier intervention meaningfully prevented CVD in all but the lowest risk individuals. Intervention at age 40 years versus age when the 5-year CVD risk reaches 10% led to an increase in quality-adjust life-years for 37/54 female individuals and 44/54 male individuals simulated and an increase in years of life lived (i.e. life expectancy) for 46/54 female individuals and 47/54 male individuals simulated. Earlier intervention was also cost effective in 5/54 female individuals and 17/54 male individuals.

conclusionsCurrent guidelines may result in certain individuals with a lower 5-year, but higher lifetime, risk of CVD being overlooked for earlier cost-effective interventions to prevent CVD.
