Perception of Biosimilar Biologics and Non-Medical Prescription Switching among Rheumatologists: A Saudi Society for Rheumatology Initiative.
Article in Saudi pharmaceutical journal : SPJ : the official publication of the Saudi Pharmaceutical Society, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers, 1 of them a synthesis that pooled 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.
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 aim of this study was to evaluate rheumatologists' perceptions of biosimilar biologics and Non-Medical Switching (NMS).
methodsA cross-sectional survey was conducted among registered members of the Saudi Society for Rheumatology. The questionnaire focused on biosimilars and NMS. Logistic regression was performed to ascertain the effect of demographics and practice characteristics on the use of biosimilars and NMS.
resultsOut of 249 SSR members, 143 completed the survey, generating a response rate of 57.4%. Of those (59.44%) were men with a mean (±SD) age and years of practice of 42.3 ± 9.13 and 10.3 ± 8.9, respectively. Rheumatologists managing adult patients (81.82%) and Ministry of Health practice (43.36 %) were the majority of respondents. Previous experience in prescribing a biosimilar was reported by 43 (30.07%) participants, with a higher probability among women (p = 0.015). A total of 26 (18.18%) participants had performed NMS on eligible patients. Adequate knowledge on biosimilars was reported by 69 (48.25%) participants. The adequacy of evidence to grant biosimilar approval for the studied indication and extrapolation to treat other conditions was reported by 88 (61.5%) and 69 (48.3%), respectively. The concept of
conclusionThere is a clear knowledge gap about the biosimilar approval process among adult and pediatric rheumatologists who took part in the survey. In addition, a large number of participants reported having negative opinions about NMS. There is a need to organize SSR-led educational activities, and develop national guidelines regarding biosimilars and NMS.
