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

backgroundThe rising cost of cancer drug therapy threatens the long-term sustainability of Taiwan National Health Insurance. Cost savings can be achieved through various strategies, e.g., using smaller vial sizes, sharing vials, weight-based dosing, or switching to biosimilars. Here we aimed to examine the cost-effectiveness of a trastuzumab biosimilar combined with docetaxel (TDbiol) for treatment-naïve HER2

methodsA Markov model with three health states was developed to assess the cost-effectiveness of trastuzumab biosimilars plus docetaxel over a 40-month time horizon in patients with HER2

resultsIn the base-case scenario, the incremental cost-effectiveness ratio (ICER) was NTD 811,050 per QALY gained. One-way sensitivity analyses showed that the model was sensitive to utilities and transition probabilities, but not particularly sensitive to the wastage assumption. In scenario analyses, the ICER was higher when applying the price for trastuzumab reference biologic (branded), than for trastuzumab biosimilar.

conclusionThe trastuzumab biosimilar combination regimen is cost-effective and offers significant drug cost savings in Taiwan.
