Most health information is verbal or written, yet words alone may not be the most effective way to communicate health information. Lower health literacy is prevalent in the US and is linked to limited understanding of one's medical condition and treatment. Pictures increase comprehension, recall, adherence and attention in health settings. This is called pictorial superiority. No systematic review has examined the impact of pictorial health information among patients and consumers, including those with lower health literacy.
This systematic review and meta-analysis will assess the characteristics and effectiveness of pictorial health information on patient and consumer health behaviours and outcomes, as well as differentially among individuals of lower literacy/lower health literacy. We will conduct a systematic search across selected databases, as well as grey literature, from inception until June 2018. We will include randomised controlled trials in all languages with all types of participants that assess the effect of pictorial health information on patients' and consumers' health behaviours and outcomes. Two independent reviewers will conduct the primary screening of articles and data extraction for the selected articles with a third individual available to resolve conflicts. We will assess the quality of all included studies using the Cochrane risk of bias tool. We will combine all selected studies and do a test of heterogeneity. If there is sufficient homogeneity, we will pool studies into a meta-analysis. Independent of the heterogeneity of included studies, we will also conduct a narrative synthesis.
No ethics approval is required. The results will be published in a peer-reviewed journal and presented at relevant conferences.

大多数健康信息是口头或书面形式的，但仅靠文字可能并非传达健康信息的最有效方式。健康素养较低的情况在美国很普遍，且与对自身病情和治疗的理解有限有关。图片能提高在健康场景中的理解、记忆、依从性和注意力。这被称为图像优势。尚无系统评价研究过图像健康信息对患者及消费者（包括健康素养较低者）的影响。
本系统评价和荟萃分析将评估图像健康信息对患者及消费者健康行为和结果的特征及有效性，以及在文化程度较低/健康素养较低个体中的差异。我们将对选定数据库以及灰色文献进行系统检索，时间跨度从起始至2018年6月。我们将纳入所有语言、所有类型参与者的随机对照试验，这些试验评估图像健康信息对患者及消费者健康行为和结果的影响。两名独立评审员将对文章进行初步筛选，并对选定文章进行数据提取，如有第三人可解决分歧。我们将使用Cochrane偏倚风险工具评估所有纳入研究的质量。我们将合并所有选定研究并进行异质性检验。如果有足够的同质性，我们将把研究纳入荟萃分析。无论纳入研究的异质性如何，我们还将进行叙述性综合分析。
无需伦理批准。结果将发表在同行评审期刊上，并在相关会议上展示。
