The effectiveness of visual-based interventions on health literacy in health care: A systematic review and meta-analysis

Limited Health Literacy (HL) is an obstacle to accessing and receiving optimal health care and negatively impacts patients’ quality of life, thus making it an urgent issue in the health care system. Visual-based interventions are a promising strategy to improve HL through the use of visual aids and pictorial materials to explain healthrelated concepts. However, a comprehensive summary of the literature on the topic is still scarce.
