Abstract：
BACKGROUND: 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 health-related concepts. However, a comprehensive summary of the literature on the topic is still scarce.
METHODS: To fill this gap, we carried out a systematic review and meta-analysis with the aim to determine the effectiveness of visual-based interventions in improving comprehension of health related material in the clinical population. Independent studies evaluating the effectiveness of visual-based interventions on adults (> 18 years) and whose primary outcome was either health literacy (HL) or comprehension were eligible for the review. After a systematic literature search was carried out in five databases, 28 studies met the inclusion criteria and thus were included. Most of the studies were randomized controlled trials and they focused on HL and health knowledge as outcomes.
RESULTS: The review and meta-analysis showed that visual-based interventions were most effective in enhancing the comprehension of health-related material compared to traditional methods. According to meta-analytic results, videos are more effective than traditional methods (Z = 5.45, 95% CI [0.35, 0.75], p < 0.00001) and than the employment of written material (Z = 7.59, 95% CI [0.48, 0.82], p < 0.00001). Despite this, no significant difference was found between video and oral discussion (Z = 1.70, 95% CI [-0.46, 0.53], p = 0.09).
CONCLUSIONS: We conclude that visual-based interventions, particularly the ones using videos, are effective for improving HL and the comprehension of health-related material.

摘要：
背景：有限的健康素养（HL）是获得和接受最佳医疗保健的障碍，并对患者的生活质量产生负面影响，因此，它成为医疗保健系统中的一个紧迫问题。基于视觉的干预是通过使用视觉辅助和图片材料来解释与健康相关的概念来改善HL的有前途的策略。然而,关于这个主题的文献的全面总结仍然很少。
方法：为了填补这一空白，我们进行了系统评价和荟萃分析,目的是确定基于视觉的干预措施在提高临床人群对健康相关材料的理解方面的有效性.评估基于视觉的干预措施对成年人（>18岁）的有效性的独立研究，其主要结果是健康素养（HL）或理解力，符合该审查的条件。在五个数据库中进行了系统的文献检索后，28项研究符合纳入标准，因此被纳入。大多数研究是随机对照试验，他们集中在HL和健康知识作为结果。
结果：综述和荟萃分析表明，与传统方法相比，基于视觉的干预措施在增强对健康相关材料的理解方面最有效。根据荟萃分析结果，视频比传统方法更有效(Z=5.45，95%CI[0.35，0.75]，p<0.00001)和书面材料的使用(Z=7.59，95%CI[0.48，0.82]，p<0.00001)。尽管如此,视频和口头讨论之间没有发现显著差异(Z=1.70，95%CI[-0.46，0.53]，p=0.09)。
结论：我们得出结论，基于视觉的干预措施，尤其是那些使用视频的人，对改善HL和对健康相关材料的理解是有效的。
