Determinants and associated factors for hallux valgus: a systematic review and meta-analysis.
Synthesis in BMC musculoskeletal disorders, 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
backgroundHallux valgus (HV) is a prevalent deformity with inconsistent evidence regarding its etiology. The objective of this review is to systematically synthesize the associated factors of HV.
methodsFollowing PRISMA guidelines, five databases (PubMed, Web of Science, Cochrane, Embase, CNKI) were searched up to November 2025. We included observational studies (including cross-sectional, case-control, and prospective cohort designs) assessing factors associated with HV. Meta-analysis was performed and expressed as odds ratios (OR) if two or more articles assessed the same factor.
resultsTwenty-three studies were included. We identified eleven factors independently associated with increased odds of sustaining hallux valgus (HV) (in order of highest to lowest OR): (1) female sex (OR 2.57, 95% CI 1.83-3.52); (2) foot pain (OR 2.36, 95% CI 1.61-3.46); (3) narrow-toed shoes (OR 2.25, 95% CI 1.64-3.07); (4) knee pain (OR 2.04, 95% CI 1.55-2.68); (5) scoliosis (OR 1.84, 95% CI 1.14-2.98); (6) high-heeled shoes (OR 1.65, 95% CI 1.27-2.15); (7) osteoporosis (OR 1.50, 95% CI 1.13-1.99); (8) knee osteoarthritis (OR 1.47, 95% CI 1.05-2.07); (9) history of stroke (OR 1.26, 95% CI 1.04-1.53); (10) flatfoot (OR 1.19, 95% CI 1.07-1.33); and (11) age (OR 1.11, 95% CI 1.03-1.20). No significant associations were found for BMI or heart problems.
conclusionHV is a multifactorial condition primarily associated with female sex, aging, and mechanical constriction from narrow footwear, which poses a greater risk than high heels. Systemic conditions like scoliosis and osteoarthritis also contribute significantly. Interventions should be multifactorial, with a strong emphasis on footwear modification.
