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

backgroundBiosimilars have the potential to increase patient access and significantly reduce healthcare costs in the US. However, uptake in the US has been slower than anticipated, limiting the benefits of biosimilar competition. Understanding the factors that affect uptake is critically important to realize the benefits of biosimilars.

methodsA US national survey study was conducted electronically from December 11, 2019 to January 8, 2020. The survey was administered to 507 US healthcare professionals practicing in dermatology, gastroenterology, hematology, oncology, nephrology, or rheumatology. The survey evaluated prescriber attitudes toward biosimilars in general, as well as prescriber decision making, using a series of hypothetical scenarios with fictional biological products.

resultsFewer than half had a baseline understanding of key elements of biosimilarity, even among respondents who had previously prescribed a biosimilar. Regardless of previous experience, all respondents benefited from receiving additional information about biosimilarity, indicating the potential benefits of educational efforts for prescribers across all specialties and levels of experience. Prescriber choice was driven primarily by formulary status; however, respondents identified a variety of factors that would influence their willingness to prescribe a biosimilar, including financial savings to the patient, pharmacovigilance, patient experience, and education on the FDA approval process. Over one-third of participants indicated a preference for reference products and nearly half indicated a hesitancy to try biosimilars until they have been on the market longer. Naming conventions for biosimilars did not affect prescribers' willingness to prescribe biosimilars.

conclusionsGaps in prescriber knowledge and hesitancy toward biosimilars remain significant challenges for biosimilar uptake. While formulary status of a biosimilar product strongly influences prescriber choice, additional prescriber education on biosimilarity is needed.
