Healthcare utilization patterns and costs related to neurofibromatosis 1 in Ontario, Canada.
Article in Orphanet journal of rare diseases, 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
BACKGROUND AND
objectivesNeurofibromatosis type 1 (NF1) is a multisystemic disease, characterized by cutaneous manifestations and peripheral nerve sheath tumors. Patients also have a high prevalence of learning disability, gliomas, as well as other malignancies, and require specialized follow up and surveillance. However, there are limited data regarding how people with NF1 use the healthcare system. We aimed to assess the use of different health services in individuals with NF1 compared to the general population.
methodsThis population-based, matched cohort study in Ontario, Canada, used a registry of individuals with confirmed NF1 from pediatric and adult clinics between 1990 and December 31, 2020, linked to administrative health databases. Each patient was matched 1:5 to population controls, by date of birth, sex, income quintile and geographic area of residence. We compared outpatient primary and specialty claims, hospitalizations, emergency department (ED) visits, same-day surgeries, overall healthcare costs and use of disability benefits.
results1,210 individuals with NF1 were matched to 6,050 controls, mean follow up was 19.6 ± 8.7 and 18.8 ± 8.5 years, respectively; at the end of the study window, mean age was 26.2 ± 16.9 years. More adults with NF1 received disability benefits than controls (17.6% vs. 6.6%, p < 0.001). NF1 individuals had more ED visits (RR:1.11, 95% CI: 1.04–1.19), hospitalizations (RR: 2.66, 95% CI: 2.43–2.91), primary care visits (RR: 1.15, 95% CI: 1.10–1.21), specialist visits (RR:2.34, 95% CI: 2.18–2.51) and same-day surgeries (RR: 1.62, 95% CI: 1.47–1.69). Healthcare costs were higher in NF1 than controls (CAD$53,858 vs. CAD$18,133, p < 0.0001). Individuals with NF1 in rural areas had more ED visits and fewer primary and specialty visits than urban dwellers; those in the highest income quintile had fewer ED visits and hospitalizations. DISCUSSION: Individuals with NF1 in Ontario, Canada, have high use of outpatient and inpatient services, disability benefits and higher healthcare costs, highlighting the need for multidisciplinary care. Rurality and income quintile were associated with the use of healthcare resources; future work is needed to assess social determinants of health in NF1.
