Selection Bias In Clinical Trials — Graphical Abstract (2025)

An infographic illustrating factors leading to health inequality. It highlights selection bias in clinical research, skewed trial populations excluding older adults, patients with co-morbidity, lower SES backgrounds, and racial and ethnic marginalized groups. It explains how non-reliable evidence creates biased clinical guidelines, resulting in unequal diagnoses and treatment, which contribute to health inequity.

Visual summary of a literature review exploring how selection bias in clinical trials leads to non-representative evidence and contributes to health inequities in the healthcare system.
