Reassurance Techniques Do Not Significantly Impact Confidence in Biosimilars for Psoriasis: A Survey of a Convenience Sample of Individuals with Self-Identified Psoriasis.
Article in Dermatology and therapy, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
introductionBiosimilars are underutilized, and negative perceptions may hinder their acceptance by patients. Psychologic interventions have not been extensively studied in the context of alleviating biosimilar hesitancy. The objective of this study was to assess the effectiveness of psychologic interventions on biosimilar confidence.
methodsFollowing institutional review board (IRB) approval, 1285 subjects with self-reported psoriasis were recruited using Amazon Mechanical Turk, an online crowdsourcing platform. Participants were randomized to one of ten groups. Group A started with a hypothetical bio-originator; group B started with a hypothetical biosimilar. The remaining groups were provided a hypothetical scenario in which they were switching to a biosimilar after achieving great results with a bio-originator, and were randomized to receive either no reassurance (group C) or one of the following psychologic interventions: reassurance of comparable effectiveness (group D), an illustration implying comparable effectiveness (group E), anecdote of great results obtained in "other psoriasis patients" (group F), anecdote of great results obtained in another psoriasis patient "a lot like you" (group G), reassurance of the rigorous evaluation process to gain Food and Drug Administration (FDA) approval (group H), engagement in a task designed to facilitate recognition of biosimilars' comparability through answering multiple choice (group I) or free response questions (group J). Confidence levels were assessed using six-point Likert scales and analyzed using one-way analysis of variance (ANOVA) and two-group t-tests.
resultsWhile no statistically significant differences were detected, illustrations implying comparability (mean 4.19), explanations of the rigorous process to gain FDA approval (mean 4.21), testimonials of treatment success in another psoriasis patient "a lot like you" (mean 4.07) and "other psoriasis patients" (mean 4.01), and engagement with multiple choice (mean 4.02) and free response answers (mean 4.08) improved biosimilar confidence compared with the biosimilar switch control group (mean 3.96).
conclusionIdentifying highly impactful methods of improving biosimilar confidence remains a challenge.
