Does higher socioeconomic status of a practice location improve clinical trial recruitment?

Higher socio-economic status of a general practice's location is positively correlated with clinical trial recruitment success, as practices in moderate and high socio-economic status postcodes demonstrate adjusted odds ratios of 1.30 and 1.83, respectively, for recruiting randomised participants compared to practices in low socio-economic status areas. This suggests that wealthier catchment areas may possess higher health literacy, better access to information, or greater research engagement.
