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

purposeThe clinical effectiveness of triple chemotherapy consisting of gemcitabine, cisplatin plus either S-1 (GCS), durvalumab (DGC), or pembrolizumab (PGC) as first-line treatment for advanced biliary tract cancer (BTC) has been reported. However, their comparative cost-effectiveness is unclear. We conducted a model-based cost-effectiveness analysis from the perspective of Japanese healthcare payer.

methodsA 10-year partitioned survival model was constructed by comparing the time-dependent hazards of the KHBO1401-MITSUBA, TOPAZ-1, and KEYNOTE-966 trials. The cost and utility came from previously published reports. Quality-adjusted life years (QALY) were used to measure the effects on health. Costs for direct medical care were taken into account. There was a one-way analysis and a probability sensitivity analysis. A willingness-to-pay threshold of 7.5 million yen (57,034 USD) per QALY was defined.

resultsThe incremental costs per QALY for GCS, DGC, and PGC in the base case study were 3,779,374 JPY (28,740 USD), 86,058,056 JPY (65,4434 USD), and 28,982,059 JPY (220,396 USD), respectively. No parameter had an influence beyond the threshold in a one-way sensitivity analysis. A probabilistic sensitivity analysis revealed that the probability of GCS, DGC, and PGC being cost-effective at the threshold was 85.6%, 0%, and 0%, respectively.

conclusionGiven the current circumstances, it is probable that triple therapy utilizing GCS will emerge as a plausible and efficient primary chemotherapy strategy for patients with advanced BTC in the Japanese healthcare system, as opposed to DGC and PGC.
