Knowledge, attitude and practice regarding scars in patients who had orthopaedic surgery: a cross-sectional study in China.
Observational study in BMJ open, 2025. 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
objectivesThis study aims to describe the knowledge, attitude and practice (KAP) regarding surgical scars among patients who had postorthopaedic surgery, and to explore correlations between these factors.
designA multicentre, cross-sectional, observational study.
settingConducted across multiple secondary/tertiary care hospitals between July and September 2024.
participantsOf 816 enrolled participants undergoing orthopaedic surgery, 54.5% were male, 43.6% were aged 31-45 years, 73.9% were urban dwellers, 31.2% had a bachelor's degree and 65.4% were married.
interventionsNone (questionnaire-based assessment). OUTCOME MEASURES: Primary outcomes were KAP scores (knowledge: 0-22; attitude: 9-45 and practice: 7-35), analysed via correlation and regression.
resultsMean scores: knowledge (12.5±6.9), attitude (27.6±3.3) and practice (28.2±6.5). Knowledge was negatively correlated with attitude (r=-0.24, p<0.001) but positively with practice (r=0.73, p<0.001). Attitude negatively influenced practice (r=-0.19, p<0.001). Multivariable analysis showed that knowledge was negatively associated with attitude (OR=0.93, 95% CI: 0.90 to 0.96) but positively with practice (OR=1.24, 95% CI: 1.19 to 1.30), while attitude was negatively associated with practice (OR=0.93, 95% CI: 0.87 to 0.999). Structural equation modelling confirmed that knowledge directly positively influenced attitude (β=21.6) and practice (β=43.3), with attitude positively impacting practice (β=7.9) (p<0.001 for all).
conclusionsPatients who had postorthopaedic surgery demonstrated poor scar-related knowledge and negative attitudes but proactive practices. Greater knowledge correlated with better practice, suggesting targeted education could optimise scar management. Further research should explore causal relationships and the efficacy of interventions.
