Prevalence and Severity of Self-Assessed Hallux Valgus in Community-Dwelling Older South African and Flemish Individuals.
Observational study in Journal of foot and ankle research, 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
introductionHallux valgus (HV) is a common foot deformity in older adults, frequently associated with pain and functional impairment. Global prevalence is estimated at 19%, although it varies by continent; consequently, there is a notable knowledge gap concerning its prevalence and severity in older populations of South Africa and Belgium. This study aimed to compare HV prevalence and severity, report on footwear habits within these cohorts, and examine associations with sex, age, and body mass index (BMI).
methodsThis observational cross-sectional study recruited 300 community-dwelling adults aged ≥ 60 years from Flanders, Belgium (n = 145) and the Western Cape, South Africa (n = 155). Demographic data, footwear habits, and HV self-assessment scores (using the Manchester scale) were collected via an online questionnaire. Associations between HV and other variables were examined using chi-square tests.
resultsHV prevalence was 27.6% in the Flemish cohort and 31.6% in the South African cohort. Although South Africans reported more frequent barefootedness, HV prevalence rates remained similar. HV prevalence was significantly higher in females (35.4%) compared to males (17.0%). Furthermore, prevalence and severity increased with age but were inversely associated with BMI.
conclusionHV prevalence is similar in older South African and Flemish individuals, despite differing footwear habits, supporting the multifactorial nature of HV formation. These findings emphasize the need for region-specific data and clinical strategies to address HV in older populations.
