The objective of the study was to determine the reporting quality of systematic review (SR) abstracts presented at World Congresses on Pain (WCPs) and to quantify agreement in results presented in those abstracts with their corresponding full-length publications.
We screened abstracts of five WCPs held from 2008 to 2016 to find abstracts describing SRs. Two authors searched for corresponding full publications using PubMed and Google Scholar in April 2018. Methods and outcomes extracted from abstracts were compared with their corresponding full publications. The reporting quality of abstracts was evaluated against the PRISMA for Abstracts (PRISMA-A) checklist.
We identified 143 conference abstracts describing SRs. Of these, 90 (63%) were published as full-length articles in peer-reviewed journals by April 2018, with a median time from conference presentation to publication of 5 months (interquartile range: -0.25 to 14 months). Among 79 abstract-publication pairs evaluable for discordance, there was some form of discordance in 40% of pairs. Qualitative discordance (different direction of the effect) was found in 13 analyzed pairs (16%). The median adherence by abstracts to each PRISMA-A checklist item was 33% (interquartile range: 29% to 42%).
Conference abstracts of pain SRs are selectively published, not reliable, and poorly reported.
本研究旨在评估世界疼痛大会（WCP）上发表的系统评价（SR）摘要的报告质量，并量化这些摘要与相应全文出版物中呈现的结果的一致性。
我们筛选了 2008 年至 2016 年举行的五届 WCP 的摘要，以查找描述 SR 的摘要。两名作者于 2018 年 4 月使用 PubMed 和 Google Scholar 搜索相应的全文出版物。从摘要中提取的方法和结果与相应的全文出版物进行比较。摘要的报告质量根据 PRISMA 摘要（PRISMA-A）清单进行评估。
我们确定了 143 篇描述 SR 的会议摘要。其中，90 篇（63%）于 2018 年 4 月前在同行评议期刊上发表为全文文章，从会议发表到出版的中位数时间为 5 个月（四分位距：-0.25 至 14 个月）。在 79 对可评估不一致性的摘要-出版物对中，有 40%的对存在某种形式的不一致性。在分析的 13 对中发现了 13 对（16%）存在定性不一致性（效果的方向不同）。摘要对每个 PRISMA-A 清单条目的平均依从性为 33%（四分位距：29%至 42%）。
疼痛 SR 的会议摘要选择性发表，不可靠且报告质量差。
