The Impact of Introducing Successive Biosimilars on Changes in Prices of Adalimumab, Infliximab, and Trastuzumab-Polish Experiences.
Review in International journal of environmental research and public health, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 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
Biosimilars are cheaper than original drugs and are thus of interest to the public. The aim of this article is to assess the benefits of introducing more than one biosimilar for the same substance (active pharmaceutical ingredient, API). The hypothesis is that the introduction of successive biosimilars of a specific original drug reduces the price of the selected API. The study focuses on drug prices varying with the successive arrival of new biosimilars. Three drugs that have at least three reimbursed biosimilars on the market were selected, two from the same therapeutic group (adalimumab and infliximab) and one (trastuzumab) representing another class of drugs. The following data were analyzed: price variation after the introduction of the first, second, and third biosimilar, and the average price reduction for all three biosimilars. Additionally, a literature review was conducted. The reimbursement of each new biosimilar is beneficial since it is associated with a price reduction in percentage terms. However, the first biosimilar brought about the greatest savings due to the higher initial prices of the original drugs and to Polish reimbursement rules. This article is helpful for when taking healthcare decisions regarding the pricing of and reimbursement for new biosimilars.
