New Approaches to Clinical Trials for Rare Diseases: Decentralized Trial Design for Neurofibromatosis Type 1 and Schwannomatosis.
Article in Cancers, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundIn decentralized clinical trials, some or all activities occur outside of traditional sites, which may reduce time away from school/work and decrease participation burden for patients and their parents/caregivers. This methodology may improve recruitment and retention in studies, which is important for rare diseases like neurofibromatosis type 1 (NF1) and schwannomatosis (SWN). Published guidance exists for the general conduct of decentralized trials, but specific considerations for clinical trial design and endpoints in NF1/SWN have not yet been explored.
methodsThe Response Evaluation in Neurofibromatosis and Schwannomatosis (REiNS) International Collaboration is a group of researchers, clinicians, and people affected by NF1 and SWN whose shared goal is to advance clinical trial methodology for NF1/SWN. In December 2023, REiNS members met to discuss the opportunities and challenges of conducting NF1/SWN decentralized trials.
resultsEndpoints that are promising for use in NF1/SWN decentralized trials include visual acuity (as tested by the computerized amblyopia treatment study HOTV testing algorithm); electronic versions of REiNS-recommended patient reported outcome measures; digital health technologies for functional outcomes; radiography and computed tomography scans for imaging outcomes; remote photography to assess cutaneous neurofibromas; "e-centralized" evaluations of neurocognitive functioning; and remote biomarkers collected with analyte stabilizing tubes and self-collection devices.
conclusionsFurther research is necessary to validate endpoints for decentralized trials for NF1/SWN and evaluate their feasibility. However, trial designs that incorporate decentralized elements hold considerable promise for rare diseases like NF1/SWN where patients encounter significant barriers to traditional clinical trial participation.
