The aim of this study was to describe the relationship among abstract structure, readability, and completeness, and how these features may influence social media activity and bibliometric results, considering systematic reviews (SRs) about interventions in psoriasis classified by methodological quality.
Systematic literature searches about psoriasis interventions were undertaken on relevant databases. For each review, methodological quality was evaluated using the assessing the methodological quality of systematic reviews tool. Abstract extension, structure, readability, and quality and completeness of reporting were analyzed. Social media activity, which consider Twitter and Facebook mention counts, as well as Mendeley readers and Google scholar citations were obtained for each article. Analyses were conducted to describe any potential influence of abstract characteristics on review's social media diffusion.
We classified 139 intervention SRs as displaying high/moderate/low methodological quality. We observed that abstract readability of SRs has been maintained high for last 20 years, although there are some differences based on their methodological quality. Free format abstracts were most sensitive to the increase of text readability as compared with more structured abstracts (Introduction, Methods, Results, and Discussion or eight headings), yielding opposite effects on their quality and completeness depending on the methodological quality: a worsening in low quality reviews and an improvement in those of high quality. Both readability indices and preferred reporting items of systematic reviews and meta-analyses for Abstract total scores showed an inverse relationship with social media activity and bibliometric results in high methodological quality reviews but not in those of lower quality.
Our results suggest that increasing abstract readability must be specially considered when writing free format summaries of high-quality reviews because this fact correlates with an improvement of their completeness and quality, and this may help to achieve broader social media visibility and article usage.
本研究旨在描述摘要结构、可阅读性和完整性之间的关系，以及这些特征如何影响社交媒体活动和文献计量学结果，同时考虑了按方法学质量分类的银屑病干预措施的系统评价。
在相关数据库中进行了关于银屑病干预措施的系统文献检索。对每篇综述，使用评估系统评价方法学质量工具进行方法学质量评估。分析了摘要扩展、结构、可阅读性以及报告的质量和完整性。获取了每条文章的社交媒体活动数据，包括 Twitter 和 Facebook 的提及次数、Mendeley 读者和 Google Scholar 引用次数。进行了分析，以描述摘要特征对综述社交媒体传播的潜在影响。
我们将 139 项干预措施的系统评价分为高/中/低方法学质量。我们观察到，尽管基于方法学质量存在差异，但系统评价的摘要可阅读性在过去 20 年中一直保持较高水平。自由格式摘要对文本可阅读性的提高更为敏感，与更具结构性的摘要（引言、方法、结果和讨论或 8 个标题）相比，这会根据方法学质量对其质量和完整性产生相反的影响：在低质量的综述中会恶化，而在高质量的综述中会改善。在高质量的综述中，两种可读性指标和系统评价和荟萃分析摘要总分的首选报告项目与社交媒体活动和文献计量学结果呈负相关，但在质量较低的综述中则没有这种关系。
我们的结果表明，在撰写高质量综述的自由格式摘要时，必须特别考虑提高摘要的可阅读性，因为这与提高其完整性和质量有关，这可能有助于提高社交媒体的可见度和文章的使用度。
