Burden of hereditary angioedema: results from a multinational survey of caregivers for adult and pediatric patients.
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
backgroundHereditary angioedema (HAE), a rare autosomal dominant disorder characterized by recurrent, potentially life-threatening attacks of cutaneous or submucosal swelling, affects patients' everyday activities and psychological well-being. Although caregivers are instrumental in helping patients cope with HAE, its impact on the caregivers' quality of life is poorly documented. Using web-based surveys (July 2022‒February 2023), this international study (Argentina, Brazil, Colombia, Croatia, Denmark, Germany, Hungary, Ireland, Norway, Poland, Portugal, Romania, and Sweden) assessed the humanistic and psychosocial burden of caregivers (≥ 18 years old) of pediatric (< 18 years) and adult (≥ 18 years) patients with diagnosed HAE.
resultsIn total, 120 caregivers completed the surveys: 54 caregivers of pediatric patients (CoPs; mean age 40.6 years; 79.6% female) and 66 caregivers of adult patients (CoAs; mean age 42.7 years; 48.5% female). CoPs and CoAs reported 5.6 and 13.1 HAE attacks (mean) in the past 6 months for individuals receiving their care, respectively. CoPs provided care for 23.5 days (mean) per month on average; in the past 4 weeks, CoPs missed (mean) 2.6 days (mean) of work, while the children missed 3.9 days (mean) of school. CoPs cited a lack of understanding of their caregiving duties from schools (20.4%), employers/coworkers (16.7%), family (13.0%), friends (13.0%), and partner/spouse (13.0%). CoPs reported impacts on their work (37.0%), sleep (37.0%), and household chores (31.5%), and restricted time with family (29.6%), spouses/partners (27.8%), and friends (24.1%). Emotional impacts on the CoPs included worry about the child's health (90.7%) and future (68.5%); CoPs themselves reported having sleep problems (24.1%), migraine (22.2%), gastrointestinal disorders (22.2%), and anxiety (20.4%). CoAs reported impacts on their work (28.8%), sleep (28.8%), and recreational activities (27.3%), leading to missing time of work (mean 0.94 days in past 4 weeks). Emotional impacts on the CoAs included worry about the health of individual they provide care for (92.4%) and future (40.9%); CoAs themselves reported having anxiety (13.6%), migraines (13.6%), and sleep problems (12.1%).
conclusionResults of this caregiver survey revealed that the caregiver role in HAE is time-demanding and adversely impacts various aspects of the caregiver's life, particularly their emotional wellbeing.
