The Long-Term Cost-Effectiveness of Tirzepatide 5 mg versus Dulaglutide 0.75 mg for the Treatment of People with Type 2 Diabetes in Japan.

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
introductionThis analysis aimed to evaluate the long-term cost-effectiveness of tirzepatide 5 mg versus dulaglutide 0.75 mg (both administered once weekly) in people not achieving glycemic control on metformin, based on the results of the head-to-head SURPASS J-mono trial from a Japanese healthcare payer perspective.
methodsA cost-utility analysis was performed over a 50-year time horizon using an implementation of the UKPDS Outcomes Model 2 developed in Microsoft Excel. Baseline cohort characteristics, treatment effects and adverse event rates were sourced from the SURPASS J-mono trial. Simulated patients were assumed to receive either tirzepatide 5 mg or dulaglutide 0.75 mg until HbA1c exceeded 8.0%, at which point treatment was discontinued and basal insulin was initiated. Direct costs were derived from the Japan Medical Data Center claims database. Future costs and clinical benefits were discounted at 2% annually.
resultsIn this cost-utility modeling analysis, tirzepatide 5 mg was associated with lower diabetes-related complication rates, improved life expectancy, improved quality-adjusted life expectancy and higher direct costs versus dulaglutide 0.75 mg. This resulted in an incremental cost-effectiveness ratio (ICER) of JPY (Japanese yen) 1,302,240 per quality-adjusted life year (QALY) gained for tirzepatide 5 mg versus dulaglutide 0.75 mg (JPY 140 = USD 1). Tirzepatide remained cost-effective versus dulaglutide over a range of sensitivity analyses.
conclusionsIn this analysis, tirzepatide 5 mg was associated with an ICER below the commonly quoted willingness-to-pay threshold of JPY 5,000,000 per QALY gained, suggesting that tirzepatide is a cost-effective treatment option for adult patients with type 2 diabetes mellitus, compared with dulaglutide 0.75 mg.
