Patients' knowledge influences practice via attitudes toward hyperuricaemia: a mediation analysis.
Article in Clinical rheumatology, 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
objectivesHyperuricaemia is a common metabolic disorder associated with gout and cardiovascular complications. This study aimed to evaluate patients' knowledge, attitudes, and practices (KAP) regarding hyperuricaemia and to explore the mediating role of attitude in different patient subgroups.
methodsThis cross-sectional study was conducted between July and August 2023 among patients with hyperuricaemia.
resultsA total of 406 valid questionnaires were enrolled, including 367 (90.39%) male. The knowledge, attitude, and practice scores were 54.34 ± 8.68 (possible range: 13-65), 23.40 ± 2.36 (possible range: 6-30), and 40.31 ± 4.92 (possible range: 10-50), respectively. Structural equation modeling demonstrated a significant direct effect of knowledge on attitude (β = 0.072, P = 0.009) and a notable direct effect of attitude on practice (β = 0.781, P = 0.015). Knowledge had a significant indirect effect on practice mediated through attitude (β = 0.056, P = 0.003). Subgroup analysis further revealed that the mediating effect of attitude was more pronounced among patients without gout symptoms, whereas behavioral engagement among symptomatic patients was primarily driven by existing attitudinal commitment.
conclusionPatients diagnosed with hyperuricaemia exhibited adequate knowledge and generally positive attitudes, which met the 70% cut-off value standard. The findings confirmed a full mediation effect, where knowledge influences practice through attitude, with this pathway being more evident among asymptomatic patients. Improving patient attitudes, especially in those without gout symptoms, should remain a key target for tailored educational and behavioral interventions to promote consistent self-management practices. Key Points • Patients with asymptomatic hyperuricaemia often underestimated the importance of preventive measures, reflected in lower attitude scores, whereas patients with gout symptoms demonstrated significantly higher knowledge, attitude, and practice scores. • Comorbidities such as hypertension or other chronic conditions were associated with lower knowledge and attitude scores, suggesting that competing health priorities may modify patient engagement. • Knowledge influenced practice indirectly through attitude, underscoring the importance of attitudinal improvement as a mediator in patient self-management. • Targeted educational interventions, such as dietary counseling, motivational interviewing, and peer-support groups, may strengthen patient attitudes and promote sustained self-management.
