The Impact of Fragile X Syndrome on Caregivers: A Systematic Review.
Synthesis in Journal of intellectual disability research : JIDR, 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
backgroundThe effects of fragile X syndrome (FXS) reach beyond the individual with the condition, profoundly influencing the well-being of caregivers and family members. The aim of this review is to synthesise current evidence on the effects of FXS on caregivers, investigate contributors to their burden and identify gaps for future research.
methodsThis review was conducted in accordance with PRISMA guidelines. A thorough search of electronic databases was performed to identify relevant original research. Two reviewers independently screened the studies for eligibility, and the quality of included studies was evaluated using the CASP tool. Key data were extracted, and a narrative synthesis was used to summarise and interpret the findings.
resultsTwenty studies involving 3474 caregivers of children, adolescents and adults with FXS were included in this review. Thirteen studies were conducted in the United States, with additional research in the United States and Canada, Italy, France, the Netherlands and Australia. Female caregivers were the primary participants in most studies. Six primary factors were identified as shaping caregivers' experiences: care-recipients' age and gender, caregivers' characteristics, disease-related factors, compromised caregiver psychological well-being, disrupted family dynamics and limited support systems or unmet needs. Challenging behaviours in individuals with FXS consistently emerge as the factor exerting the greatest influence on caregivers' psychological and practical burden.
conclusionsCaring for individuals with FXS places substantial burdens on caregivers, influenced by patient behaviour, family dynamics and limited support. Targeted, multidisciplinary interventions are needed to address these gaps and improve both caregiver well-being and care outcomes.
